A man sits at a bar and orders ten beers, and drinks them one after the other. He then orders nine, beers and drinks them as well, and this goes on and on.

So he orders seven beers and drinks them, six beers and drinks them, five beers and drinks them, and then finally four beers. After drinking these last four beers, he says to the bartender:

“I don’t understand this. The less beers I drink the more drunk I get.”
