3 mice were sitting at a bar talking about who was the toughest. "The first mouse said, I'm so tough I can eat 20 rat sack pellets without getting sick". And slams his beer on the bar. The second mouse looks at the other two and says, "yeah well I'm so tough I can race into a mouse trap, grab the cheese, eat it, catch the bar and bench press it 20 times". Then slams his beer on the bar. The third mouse looks at the other two, remains quiet... picks up his beer, skulls it and slams it on the bar and begins to walk off. One of the other mice yells out "where do you think you're going"? - to which the third replied -"going home to screw the cat".
