Three tough mice

Three mice are at a bar, having drinks, talking about how tough they are. The first mouse slams down a shot of booze, says, "Let me tell you how tough I am."

I spot a trap and go for the cheese. When it snaps, I snatch the bar and bench press it 20 or so times and before it can close I'm outa there!" and he tosses down another shot.

The second mouse slams down a shot and says, "You think that's tough? When I find a pile of d-con, I crush it and snort it like it's cocaine¹." With that he throws down another shot and slams his shotglass on the bar.

The first two are staring at the third mouse, waiting to see what he has to say for himself.

He fires down a shot of booze, throws down his glass and heads for the door. His buddies² look at each other, then at him and say, "Hey, where are YOU going?"

The third mouse says, "I haven't got time for this shit, I need to get home to screw the cat."
