The Hearing Problem
Moishe went to talk to the doctor about his wife Miriam. "Doctor, I think Miriam is deaf because she never hears me the first time and always asks me to repeat things."
"Well, Moishe" 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, Moishe goes home and does exactly as instructed. He starts off about 15 feet from Miriam in the kitchen 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?"
Miriam replies, "For the fourth time, brisket!"
