A man walks into a bar and exclaims “quick, pour me a drink before the trouble starts!”
The bartender is a little confused but, spurred to action by the man’s decisiveness, he pours the drink.
The man downs it in one go and then shouts, “quick, pour me another drink before the trouble starts!”
The bartender, curious now, pours the second drink. As he watches the man down it just as fast as before, he asks “how are you going to pay for those?”
“Oh no,” the man wails, “the trouble’s started!”
