Three tough looking rats are sitting at a bar drinking.The first rat puts down his beer and turns to the others, saying, "You know how tough I am? Well, you know that rat poison they put down in the kitchen? I eat that stuff for breakfast lunch and dinner!"The second rat looks unimpressed and says, "That"s nothing. You know those big f**king rat traps they got all over the place? Well, get this - I jump in and out of them for a bit exercise. That"s how tough I am!"The third rat knocks back his whiskey, slams the glass down on the bar and heads for the door. "Where are you going?" asks the first rat."
I'm off home to shag the cat", replies the third rat.
