Paddy’s Wheelbarrow Sex

Paddy and his wife were discussing their sex life.

Paddy said, "I want to try that wheelbarrow position tonight." 

His wife asked, "What is that?"

Paddy told her, "You bend over, put your hands on the floor Then I pick your legs up and take you from behind!"

His wife said, "Hmm, okay, I'll do it on two conditions. First, if it hurts you stop immediately and, second, ... we don't go down past my mother's house!"
