A Texan walks into a pub in Ireland and clears his voice to the crowd of drinkers. He says, "I hear you Irish are a bunch of hard drinkers. I'll give $1000 American dollars to anybody in here who can drink 30 pints of Guinness back-to-back."
The room is quiet and no one takes up the Texan's offer. One man even leaves. Five minutes later the same gentleman who left shows back up and taps the Texan on the shoulder.
"Is your bet still good?" asks the Irishman.
The Texan says yes and asks the bartender to line up 30 pints of Guinness.
Immediately the Irishman tears into all 30 of the pint glasses drinking them all back-to-back. The other pub patrons cheer as the Texan sits in amazement.
The Texan gives the Irishman the $1000 and says, "If ya don't mind me askin', where did you go for that 5 minutes you were gone?"
The Irishman replies, "Oh...I had to go to the pub down the street and try it to see if I could do it first!"
