Three women were sitting around throwing back a few drinks and talking about their sex lives. Karen said, “I call my husband the dentist because nobody can drill like he does.” Joanne giggled and confessed, “I call my husband the miner, because of his incredible shaft.”

Kathy quietly sipped her whiskey until Joanne finally asked, “Well, what do you call your boyfriend?” Kathy frowned and said, “The postman.” Looking puzzeled Joanne asked, ”Why the postman?”

“Because… he always delivers late and half the time it’s in the wrong box.”
