Sheldon:
You have about as much chance of going out with Penny as the Hubble Telescope has of finding that at the center of each black hole there's a little man with a flashlight trying to find the circuit breaker.
Sheldon:
Oh Gravity, thou art a heartless bitch
Leonard:
I just know that moving all day can be stressful and I just thought that good neighbors and some Indian food might be just what you need... plus, curry is a natural laxative and I don't need to tell you that a clean colon is one less thing to worry about.
Sheldon:
Oh, well, this would be one of those circumstances that people unfamiliar with the law of large numbers would call a coincidence.
Leonard:
[discussing Sheldon's work] At least I didn't have to invent 26 dimensions to get the math to work.
Sheldon:
I didn't invent them. They're there.
Leonard:
Yeah? In what universe?
Sheldon:
In all of them, that's the point!
Leonard:
Why did you just flash freeze a banana?
Leslie:
I'm having it with my cereal and I couldn't find a knife.
