Three mice are in a bar, just sitting around, shooting the shit, talking about how tough they are.

First mouse says "I'm so tough, I run out into the middle of the kitchen floor wearing a waistcoat and a top hat, do a Fred Astaire dance routine and run back. Because I'm not scared."

Second mouse says "I'm so tough I run out into the middle of the floor, run up the leg of the wife, sit on her nose, spit in her eye and run back down again. Because I'm not scared."

Third mouse knocks back his drink and says "I'd love to stay here and talk all day, but I've got to go home and fuck the cat."
