I found myself in a pub in near a submarine base in New London. A group of surface sailors (targets) came in.
One of the skimmers said, in a loud voice, "I hear you Bubble Heads think you're great drinkers.
I bet $5,000 that no one here can drink 20 pints of Guinness in 30 minutes."
The bar was silent, but the skimmer noticed one old Chief leaving. No one took up the bet.
40 minutes later, the Chief who left returned and said, "Hey target, is yer bet still on?"
"Sure" said the skimmer, "20 pints in 30 minutes for a bet of $5,000."
"Out Standing" replied the Chief, "so pour the pints and start the clock!"
It was very close but the last drop was consumed with 2 seconds to spare.
"OK, buddy, pay up." said the Chief.
"I'm happy to pay, here's your money" said the skimmer. "But tell me,
when I first offered the wager, I saw you leave. Where did you go?"
"Well sonny", replied the Old Chief, "$5,000 is a lot of money to a man like me,
so I went to the pub across the road to see if I could do it first....."
