John Green on The Late Late Show with Craig Ferguson 

I feel like John either only has one suit jacket or has many suit jackets that are all the same style and color, but I also feel like either one is 100% okay because it is John Green.

When he asked if John's anxiety manifests in weird ways, I just kept thinking "Puff levels are high!"

"we're excellent finders" Yes, John, yes! AVPM-reference.

The whole time I was watching this, I could feel John's anxiety, and it was making me feel anxious. Also, I am happy to FIND out he's a hufflepuff, as I am as well :) Also, it was slightly awkward when he said OCD and you see John's face just like 😐 freeze.

His face when he says "we're excellent finders." That's the face of a man who is proud of his reference.

5:29 the moment john gets a little too nerdy for craig xD

"Hufflepuffs are particularly good finders!"

I love how he subliminally slipped in a starkid reference because Joe Moses was in the audience

Watching this interview after 'Turtles All The Way Down' gives whole new understanding of what it must have been like for John in that moment. I'm sorry John! That must have been uncomfortable. You're awesome though and thanks for bringing awareness and lessening stigma about mental illness and anxiety disorders.

"They are good finders" HE MADE A STARKID A VERY POTTER MUSICAL REFERENCE"

I really want John to be on more talk/interview shows. (c'mon Jon Stewart, Stephen Colbert)

When John Green walked on it felt like I was seeing my uncle or friend walk on the show. Geez, I haven't even met him yet and he feels like my relative haha.

I love how the "excellent finders" joke went right over Craig's head while we're all sitting here laughing our asses off because John Green just referenced AVPM on national television.

I love how easily a conversation about a book can be derailed by an abscess and then change topic to Harry Potter. I wish this interview had been longer.

Am I the only one who caught John's Starkid reference! Mr.Green, you are so amazing in so many ways!!!

I'm so proud of John, someone who is profoundly anxious around large groups of people, to be so calm and confident on national TV! He did an amazing job!

Why hasn't Ellen interviewed john??!?!

John didn't keep his promise about the author photo :p

Gosh, they have such good chemistry together. Please more of this!!

who else understood the avpm reference?

John Green and Craig Ferguson are two of my favourite people... I think I can die happy now

Craig ferguson - pretty much the best late night show host there is

I love how, with all the things Hank's done, this audience's knowledge of him is "Wizard Rocker."

That starkid reference... I FOUND that amazing

John Green made a AVPM reference :D half expected Ferguson to say "what the heck is a hufflepuff"

God, this show was amazing. It's amazing that it lasted as long as it did. Feels like something this good should have gotten cancelled.

John Green and Craig Ferguson awesome!

I love them both so much. TOO MUCH AWESOME IN ONE ROOM. HEAD WILL EXPLODE.

I'm quite a fan of both these guys and this episode has somehow managed to slip my attention for over 7 years, wowzza

We're excellent finders! Ohmygod I love you even more John!

They are such dorks and I love them both dearly.

I'm a huge fan of both Craig Ferguson & John Green! When I turned on my tv to watch Craig and he was holding that book and John came in I was screaming for joy!

This is so awesome... I've always been a HUGE fan of Craig and when this episode aired in 2013 the only thing I would ever watch on youtube was the occasional cat video, and I remember thinking at the time "Some teen book author? Meh, I'd rather see someone I actually might know on the late late show, this is kinda boring" And now after spending the last 6 months watching all of CrashCourse, and BrainScoop, and SciShow and every single vlogBrothers video up to the one where Hank mentions that John was on the late late show, and starting to read some of John's Books this clip is made of so much awesome that I cannot even believe I felt so bored when i originally saw it. It makes me wonder if someone else is starting their own journey towards becoming a Nerdfighter RIGHT NOW... Maybe even someone reading this very comment.

John Green is literally perfection

This is my favourite john green interview

The AVPM reference!!!

Knowing that John made avpm reference makes me very happy, I'm surprised I haven't seen this before

Love the casual AVPM reference... shame nobody FOUND it very funny

Thank you for uploading! So excited to see this.

I hate I missed this, so glad you have it here. Thank you

Badgers can take on wolves and bears and if you read POTTERMORE you know one of the best ministers of magic was a Hufflepuff and the person who created Hogsmaede was a hufflepuff so next time you insult Hufflepuff remember this

The 'haha mmm' described me during the entire book

John SO deserves this kind of attention. He's awesome, and TFiOS was profoundly moving. Good for him!

This was so cool to see, tons of fun, thanks so much for posting it.

Yay! John Green is a Starkid fan!

John Green! you're so smooth here, I barely recognized you.

Oh I love you John!!! I was beaming the whole time while watching this.He deserves all the love and spotlight he will ever get!

I must have watched this a couple gazillion times. My two faves from different media, merging.

HUFFLEPUFF POWER

I love how you can see how uncomfortable John really is.

so awesome!!!

This video combines two of my favorite people. John Green... and Geoff.

They never mentioned anything about the book...(shrugs)

he is so sweet! He seems like a genuinely lovely person. I'd love to meet him :)

John Green, love ya!

Two of my favorite people

i don't think a lot of people in the audience understood the very potter musical reference

This was more of a advertisement for all things Harry Potter rather than anything to do with TFIOS!

Excellant! Two of my favourite people meet at last!

Literally made my entire day!

Did NO ONE catch the Very Potter Musical reference? John said Hufflepuff's are excellent finders.

"we're excellent finders"

My two heroes in one clip. Awesome!

Thank you!

Comments 75% Did they get the Very Potter Musical reference? 20% IM HUFFLEPUFF AND IM PROUD 5% oooooh OCD aaaaaaahhhhh

John lied, his new author photo isn't even close to "front and center". smh.

I just spent my afternoon crying over this book. Such a beautiful story.

I fucking love John!

I just referenced this in my university essay... life is good :'D

Starkid reference!

I am SO glad for social media and new ways in which we consume information because if it weren't for the fact that there is always readily available information to be read, I would have gotten used to just watching stuff; which is not 'less than' but it's only one of the available options.

Two of my favorite people in the world! This is awesome! :)

Okay, so this guy makes an AVPM reference and no one in the studio notices?

"And we're excellent finders..." XD

Just as adorable and awesome as always and I love how he's not letting any of this awesome fame go to his head. I feel like a proud mum, getting to watch Hank and John do so well!

Wow, nice. Love it. Impressive performance there.

HUFFLEPUFF AND PROUD OF IT

He's a famous novelist.

omgomg my two most fav ppl interacting with each other!!

I'm a Hufflepuff, and boy I am ever so much more proud.

I just came here for the StarKid reference okay bye.

EXCELLENT FINDERS. YOU GO, JOHN.

OH MY GOSH HE WATCHED AVPM

John Green is in the same house as me!!! Hufflepuff FTW!

WHAT! That is so awesome!!

This was amazing! Love Craig and John :)

THE STARKID REFERENCE GAME IS STRONG GREEN!!!!

Craig pwned John with the 3000 (pairs) of eyes LOL

Thanks for the tip. I should like to see it at some point.

@jenni Heller Props to you for linking CBS

I'm a Pottermore branded Slytherin, but an everything else branded Hufflepuff.

Yessss!! John and I are hufflepuffs!

Two of my favorite things together *.*

Love John Green and TFIOS is a wonderful book.

O the internet jokes that nobody in the studio gets!!

AVPM reference... I enjoyed Psycho reverence more! :)

John, you should have mentioned you have the "puff factor" of your hair. LOL! I love this.

John Green! With Craig & Geoff! A dream come true. Off to watch a vlogbrothers video now..

He didn't mention the rising puff levels.
