A man walks into a bar and asks the bartender for a case of beer, any kind except Schlitz. The bartender says, ?What?s wrong with Schlitz, don?t you like it?? The man says, ?I hate that shit. Last night I drank a whole case of Schlitz and blew chunks.? The bartender says, ?You drink a case of any beer you?re going to blow chunks?. ?You don?t understand? said the man, ?Chunks is my dog.?
