Three guys are in a boat on a lake in Minnesota, fishing. It's an extremely hot day so they drink a lot of cold beers. One of them stands up to relieve himself over the side, and he falls in and sinks. After a minute, the other two dive in and look for him. Finally one of them finds him at the bottom of the lake, and hauls him to the surface, where the two men take turns giving him mouth-to-mouth resuscitation. ""That's weird,"" says one, ""I didn't notice that Bill has such bad breath."" ""Yeah,"" says the other. ""And I didn't notice that he was wearing this parka.""
