Three women are sitting in a cafe, talking about their husbands.
“My husband is a miner,” says Heather. “I like being in bed with him because he has an incredible shaft.”
“Mine is a dentist,” says Linda. “I like being in bed with him because no one can drill like he can.”
“You’re both lucky,” says Martha. “My husband’s a mailman.”
“What’s wrong with that?” asks Heather.
“Well,” says Martha, “he always delivers late, and half the time it’s in the wrong slot.”
