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.
