Raj: Can we at least rent the car from Enterprise? (nobody reacts) Oh, screw you! That's funny!

Stuart: My carpal tunnel is acting up.
Sheldon: Play through the pain.

Leonard: You come to the end of the tunnel and find a large chest. What do you do? And, Howard, do not say, I feel up the large chest.
Howard: Excuse me. I'm a married man now. I wasn't going to say anything so juvenile.
Leonard: Great. What do you do?
Howard: I walk up to the large chest, bury my face in it and go blublublublublublublublu!

Leonard: Okay, there are ogre tracks and a trail of broken candy canes in the snow. Sheldon, what do you do?
Sheldon: I signal my contempt for your cruel plan to shove Christmas joy down my throat by making a gesture that says get a load of this guy.

Raj: I feel like I've been called down to the principal's office. Although I wouldn't mind if Brown Sugar suspended me. From a sex swing. (Looking at his flask) This may have been a mistake.

Raj: Insurance will replace your car, it won't defunk my junk.

Leonard: Set your phasers to stun. If we vaporize Penny, I'll never get a girlfriend that pretty again.

Amy: I have a lab full of coked up monkeys with nothing to lose.

Sheldon: Oh, a scroll. I like scrolls. They're my third favourite system of transmitting the written word, after stone tablets and sky-writing.
You have all been summoned to join a thrilling Dungeons and Dragons adventure. Your quest begins in a secret northern village of elves who have all been massacred. I like where this is heading. Your task is to rescue their leader from a dungeon of ogres. Oh, that's a saucy twist. That leader's name: Santa Claus.
No, no, no!
Leonard: Its actually ho, ho, ho, but you'll get the hang of it.

Santa: (By a cannon, pointed at Sheldon) This is for leaving me in the dungeon to be eaten alive by ogres!
Sheldon: Wait, uh, uh, hang on. In my defense
Santa: Ho, ho, ho, ya big dork. (Fires cannon)

Sheldon: My father used to say that a woman is like an egg salad sandwich on a warm Texas day.
Alex: What?
Sheldon: Full of eggs and only appealing for a short time.

Sheldon: Your ovaries are squirting so much goofy juice into your brains you don't even know which way is up.

Sheldon: My fists are not up because I'm milking a giant invisible cow.

Leonard: Okay Sheldon, to start our quest, you need to open this little Christmas gift I got you.
Sheldon: Christmas? You know I don't enjoy Christmas.
Stuart: Why not?
Sheldon: Oh, where to begin? Trees indoors. Overuse of the words 'tis' and 'twas'. And the absurd custom of one stocking. Everybody knows that socks comes in pairs. Who uses one sock?
Howard: A pirate with a peg leg?
Sheldon: Actually, that helps, thank you.

Howard: (Mimicking Bernadette in a high voice) Oh Howie, stop talking about space so much. Nobody likes it.
Bernadette: (In a low voice) I don't sound like that.
