Quiz Show: Vlogbrothers Face-Off: Hank v. John! 

I'm the Anna that John played for and I am just so excited at the number of times he said my name, and how adorable he was while losing. It is all I could have ever hoped for Also: I definitely would have lost too, John.

You could see John die a little inside whenever they made a book pun like "the Fault in our Earth."

When you realise Hank green is responsible for crash course biology and doesn't know the function of phloem

I like how John starts off asking a question then admits he doesn't know the answer. Thats a very respectful quality of an intelligent mind in my opinion.

Hank: B! John: Nope! Michael: YOU ARE CORRECT! This is siblinghood.

Hmmmm... ERB: Hank v John.

"I'm a doofus! There's no other word for it!" Oh yes there is, John, and that word is grapefruit.

Vlogbrothers battle it out on this episode of SciShow Quiz Show!

I want to see Hank and John team up in real Jeopardy, they would be unstoppable.

I liked how John was very apologetic to Anna even without starting the quiz lol

I need an "Everything is dead" shirt.

Dat sibling rivalry dough

7:55 That's gonna be a gif.

I must admit I didn't think they were going to have an actual commercial break and so I was so surprise when and actual ad came up! It was perfect!

I got the Alaska question wrong. I am from Alaska. I shall go hide in shame now.

Do one with Michael from Vsauce :3

Mom! Hank's cheating!

John's childish smile when he is introduced and he waves to the camera is, like, everything. Forever in love with this man.

After Hidden Figures, I screeched John Glenn and slapped my knee as a buzzer.

the host reminds me of someone from the capitol in the hunger games

All the time I thought: Please Hank, do not wager all of your sci show bucks at the end! He did this several times before and it just made me angry, that he lost, although he didn't have to. So before the last question I paused and wondered, how many he _should_ wager - I guessed 301. I have no words for the relieve I felt when I saw that number on his card. John chose good, but somehow irritating. Here's what they chose and possible scenarios: 1100 +/-301 = 1401 v 799 700 +/-401 = 1101 v 299 Here's how you get 301/ the mathematically solution: There are two options each (right/wrong) i.e. 2² = 4 possible scenarios: 1. Hank's right (H,r); John's right (J,r) 2. Hank's wrong (H,w); John's wrong (J,w) 3. H,r ; J,w 4. H,w ; J,r Considering J,r How many bucks could he reach? 700 * 2 = 1400 If H,w, he can't beat that. His maximum would be 1099 If H,r, he has to win x>(1400-1100) x>300 If J,w and H,w too he has to make sure, that he doesn't have less than John. If J,w, he has x *In other words 300 < x

Now that Hank has defeated John, Hank must face DAVE GREEN! (and John's next punishment should be...several hours of makeup to become Dave Green)

7:58 You should have known this Hank! You helped teach me it from Crash Course for my A Levels!

Question: is it better to actually be represented by John Green, or to win Pizza John merchandise?

That smile at 8:05 on John's face when Hank's wrong too.

You know nothing, John Green.

That was PITHetic! Ha! Great job guys! I think both Nerdfighters should get a prize!! Just a bigger one for the winner. But Everyone is a winner.

I know John is a best selling author and more famous but as a science person Hank is my favorite

:O Hank's the one who taught me about xylem and phloem!

If you guys are going to impose rules, the first one should be "hands at the edge of the table during the question"

I thought at the end John was going to say something along of the lines of "I've been to Alaska... It's coald"

Thanks so much for teaching me about Katherine Johnson!

when you realize Hank is taller than john!

The hectacare returns...

The only right way to have advertisements interrupt your video. Amazing.

Hank laughing at John's joke about hectacres made me really happy because, even though they obviously watch each other's videos, it reminded me that Hank and John are both creators and viewers on the vlogbrothers channel and that they started doing it and still do it for each other and I'm just feeling a bit sentimental

That debate at the end had me dying. XD Hank is worried about the economics of the future and John is all insulting Hank and all "AHAYAIAHAHAWOAH I'M A DOOFUS!"

I think that John represents Social Studies (US and World History) and Hank is Science. (Biology, SciShow) WHen it comes to learning topics, I support John 100%

5 pillars of islam : 1. To believe in allah and to say "i bare witness that there is no god but allah and that muhammed (PBUH) is the final messenger of allah" 2. To pray 5 times a day. 3. To pay charity. 4. To fast during ramadan. 5. To perform pilgramage to the holy city of mekkah. (To go to Hajj) Just in case if anyone was wondering after what hank said of not knowing. Now you all know, you too Hank :D

SciShow Quizshow: Family Feud Edition!

The first 30 seconds is why they are amazing, they don't pick questions they know the answers to but questions the other one knows the answers to in order to make the other brother feel good.

One of my favorite episodes of SciShow Quiz Show to date. I love seeing Hank and John together.

Yes!! I was rooting for Hank all the way. Younger siblings of the world unite!

Also, it's great that you featured female scientists and their discoveries :)

I'd love to watch these guys play a board game. Wouldn't that be soomething for Hankgames?

Did you watch that commercial though?!?! Best part of the video!!

I swear on my life that John and Hank together on videos are one of the few things on the internet that actually make me laugh out loud. A lot of things are funny in this place, but that kind of funny where you don't feel compelled to make face expressions, just laugh inside your head. But with those two I just can't help but genuinely laugh. You're both awesome.

I just got out of my organismic biology class, and we were talking about xylem and phloem, so when i saw the question about them, I was like :PHLOEMMMMMMM!". lol My professor should be proud.

I haven't watched this yet but, Hank if you lose to the Green, History Edition, then we are going to have some serious problems.

Why is it that when they are together and honest it's so hilarious and awesome?! I LOVE IT

How did Hank not know the plant tissue that carries food is called the phloem? Howw?

This video should be used as a repository for Michael faces. Seriously. Every single one of his grins is gold.

We learn abt the pith, xylem, phloem and cambium at 15 where I come from. Really surprised hank didn't know the answer

I sooo love this channel. Not only do I learn a little about science and humour - I mostly learn about human psychology (and show-man-ship, Hank) so beautifully.

yes! I've been waiting for this episode since I saw the pic on facebook! You guys need to do this show more often.

This was my favorite SciShow quiz show, though I have watched every SciShow upload and I especially love the quiz shows. DFTBA guys!

all this time I thought Hank was a lot shorter than John

I like how after they answered the questions, they inserted a clip explaining more about it. I love this channel!

how could hank not know the phloem question!!! he taught it in crash course!!!!!!

michael's face after he said looking for alaska to john is beautiful

am i the only one that actually had a commercial happen during the "commecial break"? ;D

Hello there! - geologist here. Your normal fault diagram shows a subduction zone which is not actually a normal fault at all. Subduction zones are on a much larger scale than faults and if you think about the relative displacement of the rock in the overriding continental crust with respect to the subducting oceanic crust then you actually have a reverse fault (although this still is not the best way of putting it.) A better way of describing the difference between normal and reverse faults is that normal faults are where typically younger rock slides down to rest adjacent to older rock, whereas reverse faults are generally where older rock is pushed upwards to rest next to younger rock. Great episode anyway though guys!

I watch both of there channels and had no idea they are brothers

This was a lot of fun to watch, you guys do great on screen together.

Lol, sibling rivalry it's so cute

I love the Catherine questions! It's great to hear about all these unsung heroines of science!

If there's one thing I learned in fifth grade, it's that phloem flows down like a faucet and xylem is the opposite 🙃

Love this, it's interactive, educational and entertaining. Can't ask for more.

Just noticed there are no comments on this video and I'm 4 minutes in. Dang it, there surely must be by now. My grandma's name is Catherine Johnson. fun fact.

I love how even if you don't know the answer or don't get the question correct, you can still learn something.

WAIT WHAT THEY DON'T KNOW THE DIFFERENCE BETWEEN THE XYLEM AND THE PHLOEM WHAT

I adore how they face off being nerdy and adorable.

I KNEW THE PLANT ONE!! I KNEW IT WAS PHLOEM! I AM A BIOLOGY EXPERT!!!!!! **dancesfortheminimalknowledgesheposseses**

These guys picked me up on a grim day and gave me a lot of smiles! Really, thank you for that!

Is that the author of " The Fault in Our Stars"?

I recently found this channel, and I'm kinda in love with it! I'm really happy to see you guys showcase so many women scientists. (Even if it was only for the cathrine thing) Also, it was nice getting most of the questions right.^^

Hmm. In Geography we called them destructive, constructive and conservative plate boundaries... maybe it's different in the U.K :P

This is so chaotic. Thanks, RU-vid algorithm. Also, did Hank write books just so he could be introduced as the NYT bestselling author? Or so that John could be introduced as the brother of one?

You guys should really make use of that "commercial break" Hell you could make it an ad for SciShow shirts and other knickknacks

The face Michael makes whenever he says a pun 😂

WHAT ? There's two of them ? When did that happen ?

I'm so excited there was a Katherine Esau question! I still have her Plant Anatomy text book from my college days in the 1970s - WHAT a great book.

This featured neither John Travolta nor Nicholas Cage I feel lied to

Horrible, horrible day at work, come home beaten and ragged. Open up RU-vid and get instantly happy...you guys are amazing.

I realized that I never saw both of them in the same screen / episode... Jesus!

Everything about this is so a dorkable. I love watching these older vids.

Finally I got them all right!

The dorky look on Michael's face every time he makes a pun on John's books and looks at John for a reaction XDDDD

Damn I would've won that.

7:58 the irony is that Hank did a Crashcourse episode on the Vascular Bundle which allowed me to understand it, and now he's forgetting what he taught thousands of High School Students.

I came here from a comment on today's quiz show

Love this classic intro, thanks for nostalgia

I KNEW THE PHLOEM AND COAL ANSWERS!!!! Sadly that was all I knew :/

Katherine Johnson was awarded the presidential medal of freedom in 2015 and in March 2016, principle photography began for Hidden Figures, a movie about Johnson and her African-American colleagues at NASA, set for release in January 2017.

9:22 He said Compressed. How is that not OBVIOUS

What a joy these guys are to the world of science enthusiasts. Their part in my personal science knowledge is tremendous. Thanks Green bros.!

John is a fully ripened Grapefruit.

I love Johns humour and I love their brotherly relationship omg !!!

Time: 4:02 Hank: Oh John: wow Hilarious

I got the "phloem" answer right. Now I can pat myself on the back because there was one thing I knew that John and Hank didn't, and only ten ga-billion things they know that I don't. I'm so smart.
