John and his wife are getting ready for bed. The wife is standing in front of a full-length mirror taking a hard look at herself.
"You know love," she says, "I look in the mirror and I see an old woman. My face is all wrinkled, my boobs are barely above my waist and my bum is hanging out a mile. I've got fat legs and my arms are all flabby." She turns to John and says, "Tell me something positive to make me feel better about myself."
He thinks about it for a bit and then says in a soft voice. . . .
"Well... there's nothing wrong with your eyesight."
