Harry: "The Last Supper" by Leonardo Da Vinci.
Tommy: Boy, the guy in the middle really knows how to throw a party, huh?
Harry: And he's sitting in front of the archway.
Sally: So what?
Harry: Well, the negative space in the archway draws our focus. And the hills outside the archway fade into a bluish haze, creating distance. So it's sort of like it's not just a party, it's a going-away party.
Dick: Harry, I'm impressed.
Harry: Mmm, me, too. Can we buy it?
Dick: Oh, don't be silly. After one week, we'd be sick of it.
