Bernadette: Thank you again for cooking. It's getting tough for me to be on my feet all day.
Stuart: You just kick back and relax; I've got it all under control.
Raj: Although it was already under control.
Stuart: I'm sorry, you mumbled something?
Raj: It's just that they've had plenty of help.
Stuart: Well, you know what they say. It takes a village.
Raj: Well, they already had a village.
Stuart: I noticed the village couldn't find time to put the crib together.
Raj: Yeah, well, maybe the village was too busy checking out the local Montessori school for the new arrival.
Stuart: You mean the one with the empty beer bottles in the sandbox? We'll pass, thank you.

Stuart: Oh, Sheldon, I'm afraid you couldn't be more wrong.
Sheldon: More wrong? Wrong is an absolute state and not subject to gradation.
Stuart: Of course it is. It's a little wrong to say a tomato is a vegetable, it's very wrong to say it's a suspension bridge.

Stuart: Would you mind stocking these?
Denise: Actually, I'm not on the clock today. I'm just hanging out with my boyfriend.
Stuart: Ah, cool. Huh. That's me, right?
Denise: Oh, I forgot to tell you, I broke up with you, and now I'm dating that guy.
Stuart: I know you're joking, but my flight-or-flight response doesn't.
Denise: Isn't it fight-or-flight?
Stuart: Not for me.

Stuart: Whoa, whoa. You're not gonna cut open a meteor, are you? Have you not learned anything from comic books? Space viruses? Pod people? I sell nothing but warnings.

Sheldon: If it's like your 3-D chess game, then you're out of your length, width and depth. Amy, get the Neosporin, somebody just got burned.

Leonard: Sheldon, I know what you did, now change the password back.
Sheldon: Well, powder me in sugar and call me a donut, if it isn't Leonard Hofstadter.

Sheldon: It's not my fault I'm bad at sharing; I skipped kindergarten.
