An alien walks into a bar. There is a guy sitting next to him, and the alien touches his shoulder.
The man says, "Do that one more time and I'll run you over." The alien does it again and gets ran over. They get back in the bar and he touches him again. The man says, "Do that again and I'll chop your dick off." He touches him again. The man pulls the alien's pants down and pulls out his knife. He was astonished at what he found. There was nothing there! He looks up at the alien and looks at his finger and fainted.
