A Jewish Texan buys a round of drinks for all in the bar because his wife had just produced "a typical Texas baby boy weighing 20 pounds."
Congratulations shower him from all around, and many exclamations of "Wow!" are heard. A woman faints due to sympathy pains. Two weeks later, he returns to the bar.
The bartender says, "Say, you're the father of the typical Texas baby that weighed 20 pounds at birth. How much does he weigh now?"
The proud father answers, "Ten pounds."
The bartender is puzzled and concerned. "Why? What happened? He already weighed 20 pounds at birth."
The Texas father takes a slow swig from his long-neck Lone Star, wipes his lips on his shirtsleeve, leans to the bartender and proudly says, "Had him circumcised."
