Three old men are discussing their sex lives.
The First man says, "Last week, my wife and I had great sex. I rubbed her body all over with olive oil, we made passionate love, and she screamed for 5 minutes at the end."
The Second man boasts, "Last week when my wife and I had sex, I rubbed her body all over with butter. We then made passionate love and she screamed for 15 minutes."
The Third man says, "Well, last week my wife and I had sex too. I rubbed her body all over with chicken fat, we made love, and she screamed for 6 hours."
The First and Second men were stunned. They replied, "What could you have possibly done to make your wife scream for 6 hours?"
"I wiped my hands on the drapes."
