An American walks into an Irish pub. He asks the patrons, "I'll bet $500 that none of you can drink 10 pints of Guinness in 10 minutes." People raise their heads, but ignore the absurd bet and go back to drinking and merrymaking, except an Irishman who leaves the bar. Some time passes and the Irishman comes back to the pub and approaches the American. "Is yer bet still on the table?" The American replies, "Sure it is! Bartender, get this man his drinks." The bartender lines up 10 pints of Guinness on the bar. The Irishman starts drinking and drinks up all the Guinness in less than 5 minutes. Astonished, the American hands over the money and asks, "Well, may I ask where you went earlier? Did you go to prepare in some ancient Irish way?" "Nah. I went to the pub next door first to see if I could do it."
