Sheldon: Virgin diet cuba libre please.
Penny: OK.
Sheldon: In a tall glass with a lime wedge.
Penny: Oh I'll wedge it right in there.

Amy: Gentlemen, as much as I'm sure Sheldon would enjoy playing intergalactic make-believe, he and I have other plans. We are attending my Aunt Flora's 93rd birthday party. Sheldon: Just tell her I can't come. Amy: She'll be disappointed if we don't show up. Sheldon: She's 93. She won't be disappointed for very long.

Leonard: We'll miss you Sheldon.
Sheldon: Yeah, well, who wants to spend the whole weekend, running around a bunch of pretend planets, battling made up monsters? That's for babies.
Howard: Yeah, but it's got lightsabers.
Sheldon: Please, Amy! It's got lightsabers!

Sheldon: Bongo solo!

Sheldon: I play bongos while walking down the stairs.
*Sheldon falls*
Sheldon: Never play bongos while walking down the stairs

Penny: Where are you going?
Sheldon: Wherever the music takes me, kitten.

Sheldon: That's no reason to cry. One cries because one is sad. For example, I cry because others are stupid, and that makes me sad.

Sheldon: It took me a gallon of urine to get that water!

Sheldon: Rise and shine sleepy head, half the town probably is dead.

Sheldon: # Nobody knows the trouble I've seen. Nobody knows my sorrow. #

Sheldon: Action.
Penny: Okay, it's not a movie. It's improv. So no one calls action.
Sheldon: Hey, you taught me something. Who would have thought that.

Sheldon: If you plan on having children I suggest you switch from briefs to boxers. Your testicles look a tad warm.

Sheldon: Amy, I find myself wondering if we should actually engage in coitus at least one time in our relationship. Bazinga! Bedtime. Please show yourself out.

Sheldon: If you're interested I can send you a link to a YouTube video that would show you how to perform your own rectal exam. Helpful hint: trim your nails first.

Kripke: Well, as long as we're here, I might as well take a leak.
Sheldon: Kripke, you're in my spot.
