a guy and an alien at a bar
There is a guy sitting at a bar. After a little bit, an alien walks in and sits next to him. The alien has a few drinks and leans over to the guy and touches him with his finger and says “zap.”
The guy ignores him the first couple of times. After a while though, he starts to get annoyed. First he asks the alien to stop, then starts demanding, then the guy threatens to pull the alien’s pants down in front of everybody.
The alien keeps on “zapping” him. So the guy turns around and pulls his pants down, where he discovers the alien doesn’t have a dick. The guy is pretty confused, so he asks the alien how he has sex if he doesn’t have a dick.
So the alien leans towards him, touches him, and says “zap.”
