Penny: Bug report: when a guy asks me to spend some time with him, maybe he plans something a little more interesting than hanging out at home and watching TV.
Leonard: Even Doctor Who?
Penny: Even Doctor Who.

Penny: At one point, they had me figure out how to get a banana out of a puzzle box.
Leonard: Wait, Sheldon gave me a banana in a box. He was testing me, too.
Penny: Unbelievable.
Leonard: And how could a chimp even solve that? That was impossible.
Penny: Really? You couldn't get it out?

Leonard: If I take it off, Sheldon wins.
Penny: Sweetie, every night you don't kill him in his sleep, he wins.

Sheldon: Woman, you are playing with forces beyond your ken.
Penny: Yeah, well your Ken can kiss my Barbie.

Howard: [Chuckles] Look at that. There's finally a woman in your life you can talk to.

Sheldon: Now, today's episode of 'Fun with Flags' is not fun, but it is important. Flags: You gotta know how to hold 'em, you gotta know how to fold 'em.

Leonard: I missed you.
Penny: You see me all the time. You sure you don't just miss the sex?
Leonard: Well, yeah, the sex with you is pretty great. Have you ever tried it?
Penny: I have. You're not wrong.
