Amy: I'm a girl.
Bernadette: Oh well maybe you could join us. I'll ask Penny.
Amy: No need, Penny and I are very close.
Leonard: You are?
Amy: Yes, In fact our mensies are synchronized.

Penny: You locked them in your basement?
Dr. Lorvis: Well, they're not locked in. The door just sticks.
Penny: Okay, so how do they unstick it?
Dr. Lorvis: They'd need the key.

Penny: Okay, you can't just go chasing after every girl who's nice to you.
Dr. Lorvis: Well, that's not what Sheldon says, and he seems to know his way around the ladies.

Howard: Sheldon, don't take this the wrong way, but, you're insane.
Leonard: That may well be, but the fact is it wouldn't kill us to meet some new people.
Sheldon: For the record, it could kill us to meet new people. They could be murderers or the carriers of unusual pathogens. And I'm not insane, my mother had me tested.

Leonard: [to a "smiling" Sheldon] We're here to see Koothrappali, not kill Batman.

(Sheldon smiles in a grotesque way).
Howard: Oh crap that's terrifying.
