Leonard: I know what you're doing. You're trying to get attention so we'll feel bad for you, but it's not happening.
Sheldon: No, what I'm doing is trying to figure out how to live my life now that everyone is leaving me.
Leonard: Will you knock it off? We're across the hall.
Sheldon: As the kids are saying today, "talk to the hand."
Penny: They're not saying that.
Sheldon: They are in 2003.
Penny: No, no. They're really not.
