Stuart: What's wrong with Christmas?
Sheldon: Where to begin? Trees indoors, overuse of the words "tis" and "twas," and the absurd custom of one stocking. Everyone notice socks belong in pairs. Who uses one sock?
Howard: A pirate with a peg leg.
Sheldon: Actually, that helps. Thank you.

Howard: You see, I have to play Dungeons and Dragons ... for the marriage.
Bernadette: You're an idiot.
Howard: I'm your idiot.

Sheldon: Is anyone else troubled by the Spider-Man theme song?
Leonard: Why would it trouble you? It's like your third favorite cartoon theme song.
Sheldon: It is, right behind [Sheldon sings "Inspector Gadget" and "Teenage Mutant Ninja Turtles" theme songs]
Sheldon: However, the Spider-Man lyrics posit that Spider-Man's Spider-Man does whatever a spider can.
Howard: Yeah, so?
Sheldon: I can think of many things that Spider-Man can't do that a spider can. One crawl in your ear and die, two legally leave Guatemala without a passport, and three have sex with a spider.

Sheldon: Don't try to change the subject. This is about a parking space. It has nothing to do with cars.

Howard: Do you expect me to build this?
Sheldon: I expect you to wipe the pudding off your chin. Gentlemen.

Howard: Boy, if these walls could talk.
Leonard: They'd say, "Why does he touch himself so much?"
Howard: Yeah.

Howard: So, this one's on God.
Bernadette: That might be a little more convincing if you didn't have a mouth full of bacon cheeseburger.
Howard: My religion's kinda loosey-goosy. Basically, as long as you have your schmekel clipped and don't wear a cross, you're good.

There's the problem. You can't beat Hawking like that. He hates to lose. Everyone knows the guy's a big baby. I mean, forget the wheelchair, he should be in a stroller.

Howard: Two weeks ago I was an astronaut.
Bernadette: Yeah, well, now you're a Smurf. Keep walking.
