"I've had it with my wife." said the one drinking buddy to the other in the Bar. "I am filing for divorce."
"Sorry to hear that pal." said his friend. "But, may I ask why?"
"I found her with supply of birth control pills." said the first.
"Listen Buddy, with all due respect to your religion, I just can't see leaving your wife for what the Church says is a sin."
"It isn't just that." stormed the First. "It's because I had a vasectomy over five years ago and she knows that."
