Big Bang Theory Quote
(Penny has innocently taken an onion ring from Sheldon's plate of food)
Penny: I didn't know. I'm sorry.
Sheldon: Well, I'm sorry, but that is your second strike.
Penny: What?
Sheldon: You have two strikes. Three strikes, and you're out.
(Penny looks at him blankly)
Sheldon: It's a sports metaphor.
Penny: A sports metaphor?
Sheldon: Yes, baseball.
