Marshall: Oh, hey, by the way, if anyone wants to come over early Thursday, we can watch the Slapsgiving day parade.
Barney: Well, there, you said it again.
Marshall: Said what?
Barney: Slapsgiving.
Marshall: Oh, I guess I did. You know why? I've invented a new holiday: Slapsgiving. It's the one day we set aside each year to gather together and give slaps.
