|A man sits down on a bar stool and tells the bartender, "Pour me a drink before the trouble starts."|
The bartender looks puzzled, but pours him a drink. The man chugs it and says, "Pour me another drink before the trouble starts."
The bartender does and the man downs it as quickly as the first.
After a few more rounds, the bartender says, "Look pal, you've had five drinks and all you talk about is 'some trouble starting.' Just when is this trouble supposed to start?"
The man replies, "Just as soon as you discover I don't have the money to pay you for these drinks!"
