A policeman drives by a bar late one night, after closing time, and notices two male patrons, obviously drunk, lying on the sidewalk in front of the establishment. When he parks the squad car and approaches, he notices that one of the men has his finger up the other ones exposed ass. When the policeman asks just what is going on, the owner of the finger states, "My friend here is very drunk and I'm trying to make him throw up". The policeman informs the fellow that normally you would make someone throw up my putting a finger into his throat, not his ass! The drunk replies, "When I put this finger down his throat, I guarantee you he WILL throw up!"
