A Texan, visiting Ireland
A Texan, visiting Ireland, goes into an Irish Pub, reaches in his pocket, and takes out 5 one-hundred dollar bills, places them in a stack on the bar and announces:
"I'm from Texas and I'll give $500 to any Irishman who can down 10 pints of Guinness without stopping!"
A general buzz emanates from the patrons. No one accepts the challenge, but the Texan notices that one Irishman gets up, passes by the Texan and exits the pub.
Since no one has accepted the challenge, the Texas pockets the stack of one-hundred dollar bills.
About 20 minutes passes and the Irishman re-enters the pub, walks up to the Texan and asks:
"Is the bet still on?"
"Sure", says the Texan, who reaches in his pocket and puts the stack of bills back on the bar.
The bar tender lines up 10 pints of Guinness on the bar and the Irishman proceeds to knock them back, one-after-another, without respite.
Astonished, the Texan hands the Irishman the $500, but says: "May I ask you a question?"
"Aye", replies the Irishman, "What is it?"
"Where did you go when you left the pub a while ago?"
"Why, I went to another pub to see if I could do it!" is the reply.
