A Jamaican man bought a round of drinks for everyone in the bar,
 announcing that his wife had just given birth to "a typical
 Jamaican baby boy weighing 20 pounds."
 
 Congratulations showered him from all around, and many
 exclamations of "Wow!" were heard. A woman fainted due to sympathy
 pains.
 
 Two weeks later, he returned to the bar. The bartender said, "Say,
 you're the father of the Jamaican baby who weighed 20 pounds at
 birth. How much does he weigh now?"
 
 The proud father answered, "Fifteen pounds."
 
 The bartender was puzzled. "Why? What happened? He weighed 20
 pounds at birth?"
 
 The Jamaican father took a slow sip from his Red Stripe beer,
 wiped his lips on his shirtsleeve, leaned into the bartender and
 said, "Had him circumcised."
