Remember this scene from When Harry Met Sally where Harry and Jess are at the ballgame? 

Harry: So I go to the door, and there were moving men there. Now I start to get suspicious. I say, "Helen when did you call these movers?", and she doesn't say anything. So I asked the movers, "When did this woman book you for this gig?" And they're just standing there. Three huge guys, one of them was wearing a T-shirt that says, "Don't f*** with Mr. Zero." So I said, "Helen, when did you make this arrangement?" She says, "A week ago." I said, "You've known for a week and you didn't tell me?" And she says, "I didn't want to ruin your birthday."
(They do the wave again.)
Jess: You're saying Mr. Zero knew you were getting a divorce a week before you did?
Harry: Mr. Zero knew.
