Irish baby

An Irishman was drinking in a bar in London when he gets a call on his mobile phone.
He orders drinks for everybody in the bar as he announces his wife has just produced a typical Irish baby boy weighing 25 pounds.
Nobody can believe that any new baby can weigh in at 25 pounds, but the man just shrugs,
"That's about average up our way, folks...like I said - my boy's a typical Dublin baby boy"
Two weeks later the man returns to the bar.
The bartender says, "Say, you're the father of that typical Irish baby that weighed 25 pounds at birth, aren't you?
Everybody's been makin' bets about how big he'd be in two weeks... so how much does he weigh now?"
The proud father answers, "Seventeen pounds".
The bartender is puzzled and concerned. "What happened? He was 25 pounds the day he was born."
The father takes a slow swig of his Jameson Irish Whiskey, wipes his lips on his shirt sleeve, leans into the bartender and proudly says...
"We had him circumcised”…..
