Texas baby

A Texan Is drinking in a New York Bar. He gets a call on his cell phone. He hangs up, grinning from ear to ear and orders a round of drinks for everybody in the bar because, he announces, his wife has just produced a typical Texan baby boy weighing 25 pounds.
Nobody can believe that any new baby can weigh in at 25 pounds, but the Texan just shrugs, "That's about average back home, folks. Like I said, my boy's a typical Texan baby boy."
Congratulations showered him from all around and many exclamations of "WOW!" were heard. One woman actually fainted due to sympathy pains.
Two weeks later the Texan returns to the bar. The bartender says "Say, you're the father of that typical Texan baby that weighed 25 pounds at birth, aren't you? Everybody's been makin' bets about how big he'd be in two weeks. We were gonna call you ... so how much does he weigh now?"
The proud father answers, "Seventeen pounds."
The bartender is puzzled and concerned. "What happened? He already weighed 25 pounds the day he was born.
The Texan father takes a slow swig from his Lone Star, wipes his lips on his shirt sleeve, leans in to the bartender and proudly says, "Had him circumcised."
