One more bar joke....

[Beer Snob-50]

texan walks into an irish pub and offers 5oo dollars to anyone who can drink 10 pints of guiness in 30 minutes. no one takes him up on his offer and one patron walks out of the bar. he returns 30 minutes later, drinks the 10 pionts in less than 30 minutes and collects his money. the texan asked him why he left, and he said he went to the pub down the street to see if he could do this first.
