Norm: What are you doing, Cliff?
Cliff: What? Well, I'm, uh, leaving a tip there for Carla.
Norm: Yeah?
Cliff: Yeah, one of the oldest bar tricks in the book there, Normie. Look, you see I filled the glass with water. I'm gonna invert it on top of this dollar bill. Put it on the bar, right? Looks... Looks, uh, empty now, doesn't it?
Norm: Mm-hmm.
Cliff: Well, watch what happens when she comes to get her tip. Fasten your seat belts and wait for the fun to begin.
Carla: Oh.
[Carla inverts the glass, takes the note and then throws the water in Cliff's face]
Carla: Thanks for the tip, Cliff.
Cliff: Uh, joke's still on her. She's the one that's got to mop up all this mess. [Carla wipes Cliff's face with the mop] Thank you, Carla. Your apology's accepted.
