A group of American tourists walked into a pub in Dublin.
One of the Americans said, in a loud voice, "I hear you Irish think your great drinkers. I'll wager €5,000 that no-one here can drink 30 pints of Guinness in 30 minutes."
The bar went silent, the American noticed one Irishman leaving, no-one took up the bet. 40 minutes later the Irishman who left returned and said "Hey Yank, is your wee bet still on?"
"Sure" said the American, "30 pints in 30 minutes for a bet of €5,000."
"Grand pour the pints and start the clock." It was very close but the Irishman managed to consume the last drop with 2 seconds to spare.
"Ok yank, pay up."
"I'm happy to pay, here's your money" said the American. "But tell me, when I first offered the wager I saw you leave. Where did you go?'
The Irishman replied, "Well sir, €5,000 is a lot of money to an Irishman, so I went to the pub across the road to see if I could do it."
