Let the guy you know play. You know the one. He has halitosis, dandruff, doesn't believe in deodorant or personal apace, can never remember to use his indoor voice when he is excited, and he always gets excited. If you don't know that guy, he at least reminds you of a couple of people. You can let those people play instead. After two or three games session you won't have to worry about the DM's girlfriend anymore.
