Pranks and Practical Jokes | The Big Bang Theory 

That chemical reaction on Kripke and the staff was priceless

"I tried to scare an Indian with a snake" lmao🤣

Howard's 'Sheldon' costume is still by far one of the most hilarious moments of the series.

You left out one of the best pranks. The one where they showed Sheldon a card trick where Howard guess what card you're holding, challenged him to figure it out, only to reveal at the end they'd been tricking him and whoever does the trick with Howard just agrees with whatever he guesses, right or wrong.

1:17 - 2:27 I can't with Kripke's helium prank 💀🤣 *"KRIPKE, I FOUND THE NOZZLE! I’M GOING TO KILL YOU!"*

I think the one that Sheldon did to Leonard with the sweater is pretty cruel.

"How could I be so STUUUUUUUUUUUUUUUUUUU!!!!"🤣🤣🤣🤣🤣🤣

2:21 his other three friends enjoying it with everyone else is icing on the cake 😂

Nothing beats I mean NO PRANK in the entire show beats howard cosplaying as Sheldon 😂

That sweater thing was one of the worst thing Sheldon has done to Leonard, totally get it when Leonard slap him so hard after his nobel win.

Howard playing Sheldon shows just how truly amazing an actor Simon Helberg really is.

9:56 I like the couch cushion prank that Sheldon did to Leonard and 8:12 the mailbox prank that Leonard did to Sheldon were best.

Leanord's reaction at 14:02 is priceless lmaoo

My favorite one was either when Howard dressed up as Sheldon or when Kripke put helium gas in Sheldon's office.

These pranks are hilarious 😂😂😂😂😂

GREAT video to post on April Fool's day!

8:13 Sheldon's Scream it Just Feels Right When He got Pranked

10:40 is literally me

The fact Sheldon is always involved in any way on this makes you think

Is Barry’s prank the reason they didn’t have enough helium for their experiment later on

Sheldon pranks sometimes backfire and work, but the curls one of them is the sweater one. I think Leonard is not going to forget this one.

It always gets me when Sheldon calmly goes, "Oh dear," when he realises what's about to happen 🤣🤣🤣

well i am moving back to india whats your plan 🤣

4:25 It was at this moment that he knew…he fūcked up

The "Dr. Beverly Hofstadter MD" spinoff starts filming today!

10:38 my reaction to snakes

2:35 :0 Bro that liquid shapeshifted! Hi.

The last part impersonating was osm🤣🤣🤣

I liked when Howard did Sheldon's laugh.❤😂

I don't know how Leonard didn't murder Sheldon over that sweater bit

1:14 look at him!

14:27 the fact that Howard does actually listen to Sheldon when he spouts random facts lol. How would he have thought to learn such a fact otherwise?

Dam it. You cut off the helium one to soon 😂😂😂😂

Well, Roman Emperor Elagabalus would agree with Sheldon!

It's a shame you didn't include the part when Sheldon did his application to go to Mars and hit Leonard with a pie in the face, that was hilarious.

I know a few CalTech graduates and there is quite a tradition of practical jokes

Brobdinagian 😂😂😂

9:10 that's why Joy buzzers are banned unless need a jump-start

They are in trouble

Missed a couple of good ones: the wormhole prank and the Halloween prank on Sheldon by Howard, Raj and Leonard!

When Sheldon is talking to the phone his voice change

Throughout the show Sheldon only considers raj to be an equal He only calls raj as sir or doctor

I can't believe Raj actually dropped a bar😂

2:35 8:10 How to do this ? Details please

Kripke was a menace , I love him.

Kripke was one of the most underrated characters on this show! He’s such a Wiot!!😂

4:25 note to self never sign your art in pranks

Sheldon deserve a statue for this iconic role

@jackhsu3458 It was not. Leonard literally didn't have to wear the sweater. He wore it because he wanted to prove to Sheldon that he could live with the anxieties that Sheldon lives with every single minute of every day, with the way Sheldon feels about many social conventions, as the itching of the sweater represented the 'madness' of Sheldon's brain. Leonard didn't have to do it, but he wanted to because he arrogantly assumed he could do it and prove Sheldon wrong. And he lost. This is my issue with comments like yours: you blame Sheldon for, literally, Leonard's own choices! He didn't have to tolerate anything Sheldon demanded from him, he chose to tolerate it. This is why this whole storyline proved once and for all that Leonard didn't have a spine, balls, or any kind of personality. Leonard often assumed things about Sheldon, arrogantly wanted to prove him wrong, and then failed - and it was all his own doing! That is a FACT! So Sheldon didn't do anything to Leonard here, Leonard, as always, did it to himself!

My favorite one is when Sheldon jumps out of the couch. I’ve seen it over and over and over and over and love it every time it is so funny.

13:50 those seem to be the mottling of an allergic reaction

Sheldon - most popular Howard- funniest character

8:13 Explain Texas Vs New Jersey joke please?

Leonard: Didn't you say you're making hydrogen sulfide gas? Sheldon: Yes. Leonard: Isn't that flammable? Sheldon: Highly. Oh dear. (KABOOM) 6:59 7:06

Couldn't get enough of Big Bang Theory ever!

2:30 well done cutting out the punchline, gj......

Anyone noticed that President Siebert was changed

I listen to Science Friday on NPR every week.

It always made me laugh that Howard/Raj (especially Howard) would get some if he got some tattoo sleeves. Thinking he would get lucky. He almost got lucky but it really didn't work. Lol! Poor Howard doing something stupid to get something he couldn't get. Lol!

What does Brobdingnagian mean?

And then.. Leonard says: You may be from "Texas" but I am from "NewJersey"..😎

0:56 actually you can’t

13:20, Bazinga

Leonard Hofstadter = Stan Marsh Sheldon Cooper = Kyle Broflovski Howard Wolowitz = Eric Cartman Raj Koothrappali = Kenny McCormick Stuart Bloom = Butters Stotch

The bazinga is just as bad as did I do that

The helium prank was hilarious I was dying laughing when I was little 😂😂😂

One word BAZINGA

Ohhhh. The red jumper makes me uncomfortable.

“Put’er there, you ol’ so-n’-so!”

12:34 Which Super mario bros movie the old one or the 2023 one.

I don’t know by I think it’s because of his childlike nature he can be pretty impulsive that means he’s breaking the rules in a playful way

I absolutely used to love the character of Sheldon Cooper in my 20s Now, in my 30s, I absolutely hate him cause everyone acts like him

At 13:40, Amy is wondering if she'll still have an alive boyfriend within five minutes.

Why didn't he wear a t shirt under the sweater?!?!??

The last two pranks were going a bit too far, that's just my opinion.

BAZINGA!

Belgium 🤑

Can't you die breathing helium If you are sitting in a room full of helium I think it would kill you

I wanna say Sheldon might have the most strength if not by a lot out of the group his dad was a football coach even if didn't want he must have some training

Wow

I said oh when the thing fall down

Really if u close your eyes n hear him he doesn't talk like Sheldon neither the way he walk he over did it

Interesting!!!!!!

😂😂😂😂😂😂

Idk why so many people hated it but it was most satisfying episode for me where he had to put that sweater

Honestly, the sweater/DVD episode made me very much dislike the Sheldon character. It was malicious, evil and sociopathic. It showed me a side of Sheldon I did not like.

howard dressing as Sheldon really drives it home that this show isn't laughing with its nerd viewers but still laughing at them.

Basenga

😂😂😂😂😂😂😂😂😂😂

Not “irritable”, it would be “irritating”.

A brobdinagian monstrosity? Really?

Does Leonard know you can wear something under a sweater?

8:52 THIS is the best prank, ESPECIALLY because Sheldon's richly deserved comeuppance is self-inflicted.

Test.....123456...

for weeks it's been this bad.....farke won't play inform players.....as usual no plan B. Firpo is a liability

I hate this show so much… how can young Sheldon be so good and this be so incredibly bad

Oh dear. I keep looping that gas mask over and over and now I'm getting faint from laughter 😂😂😂😂😂😂😂😂

How did Sheldon know which cushion Leonard was going to sit on?
