A leper walks into a bar, sits down, and orders a clod beer. The leper is sitting there, enjoying his beer, when he notices a man across the bar, staring at him, with an expression on his face like he is about to puke. The leper tries to ignore the man, and enjoy his beer, but the man keeps staring, and making faces. So finally, after suffering the mans stares for long enough, the leper stands, and calls across the bar, Hey man, whats your problem?? Im a leper, you know it, I know it, everyone knows it. I cant help it. Why do you have to be such an ass?

. the man, with the same grossed out look on his face replies, Its not you, the guy behind you keeps dipping his chip in your neck!.
