An American tourist strolls into an Irish pub while vacationing abroad. He is the loud cocky sort and yells out to the customers gathered in the pub, Hey, I heard you Irish were pretty good drinkers, I challenge anyone in this pub to a bet, I will bet one thousand american dollars that not a one of you can down 30 pints of beer in 30 minutes. Well, nobody responds but one Irishman in the back slips out the back door. About 40 minutes later he returns to the pub. He says, hey Yankee does your bet still stand? The American says yup, sure enough the Irishman knocks down 30 pints of beer in his 30 minutes, After he polishes off the last one and collects his winnings the american asks him. I couldn't help but notice you left the bar after I made the challenge, why? The Irishman says to him, well frankly sir that is a lot of money to me. I wanted to go to the pub across the street and make sure I could do it first.
