The deaf wife

This is one of my all-time favorite jokes:

The Deaf Wife 

A concerned husband went to a doctor to talk about his wife. He says to
the doctor, "Doctor, I think my wife is deaf because she never hears me
the first time and always asks me to repeat things." "Well," the doctor
replied, "go home and tonight stand about 15 feet from her and say
something to her. If she doesn't reply move about 5 feet closer and say it
again. Keep doing this so that we'll get an idea about the severity of her
deafness".

Sure enough, the husband goes home and does exactly as instructed. He
starts off about 15 feet from his wife in the kitchen as she is chopping
some vegetables and says, "Honey, what's for dinner?" He hears no
response. He moves about 5 feet closer and asks again. No reply. He
moves 5 feet closer. Still no reply. He gets fed up and moves right behind
her, about an inch away, and asks again, "Honey, what's for dinner?"

She replies, "For the fourth time, vegetable stew!"
And under her breath she's saying, "You stupid idiot!"
