Two guys wandered into a bar. One of the men shouted to the barkeeper, "Hiya, Mike. Set 'em up for me and my pal here."
Then he turned to his slightly dim partner and boasted, "This is a great bar. For every two drinks you buy, the house gives you one. And the pinball machines in the back are free!"
"That's not so great, responded the friend. There's a bar across town that'll match you drink for drink, and you can get laid in the back for free."
"Where is this place?" the first guy exclaimed. "Oh, I don't know," the dim fellow replied, "but my wife goes there all the time."
