Big Bang Theory Quote
Penny: Okay, what is going on?
Sheldon: Well, ever since Amy started working with Howard, she hasn't been home.
Penny: Didn't that just start this morning?
Sheldon: And has she been home?
Penny: You know, that would frustrate me. Does it frustrate you?
Sheldon: I-it does.
Penny: I get that. You know, it's okay to feel frustrated when things aren't going your way.
Sheldon: I suppose. Ah, maybe it's not that big a deal.
Penny: No. No, no. Your feelings are valid. Now, why don't you go wash up and we'll call you when dinner's ready.
Sheldon: Okay.
Leonard: (Sheldon leaves) What did you do... are you a witch?
Penny: No, I've been reading Bernadette's parenting book. It's like the answer key to the Sheldon test.
Leonard: That's amazing.
Penny: I know. But, you know, it's only birth to five. What do we do when he turns six?
Leonard: Take him to the zoo and leave him there.
