Sheldon: (Pointing as they walk to the end of the long line waiting for the Indiana Jones movie) This is where we could have been if we hadn't stopped for dinner. This is where we could have been if Koothrappali hadn't ordered dessert.
Rajesh: Well I earned it dude, I ate all my broccoli!
Sheldon: And here's where we are, the runts in a large litter, unlikely to ever reach the nourishing teats of Indiana Jones.
Leonard: So I guess it's a good thing we stopped for dinner.
Sheldon: Heah heah!

Amy: So anyway, to make a long story short, it turns out I have an unusually firm cervix.
Penny: You know, Amy, when we say girl talk, it doesn't just have to be about our lady parts.
Amy: Shame, cause I have a real zinger about my tilted uterus!

Bernadette: You know what I really love about Howard? His chest hair.
Penny: Howard has a hairy chest?
Bernadette: No, just the one, but it's really long.

Amy: Bernadette, truth or dare?
Bernadette: Truth.
Amy: Alright, to what temperature must you heat beef in order to kill the prion that causes bovine spongiform encephalopathy?
Bernadette: Umm...
Amy: Remember, you have to answer honestly.
Penny: Wait, no Amy, you're supposed to ask her something personal, or embarrassing.
Amy: Oh, alright. What is the circumference of your areolas?

Sheldon: As Captain Jean-Luc Picard once said, "The line must be drawn here! This far, no farther!"

Captain Picard (Patrick Stewart) uttered the line in the 1996 science fiction movie Star Trek: First Contact.

Sheldon: Why is there never a pontoon plane when you need one?

Sheldon is referring to a scene from Raiders of the Lost Ark, a 1981 action adventure movie where Harrison Ford is running for his life towards a pontoon plane while being chased by natives.
