Check Up

CHECK UP
At his wife's insistence, Goldberg finally went to his doctor for a check up.
"You look just terrible," said the doctor. "Do you drink?"
"Why yes, plenty." said Goldberg. "I start every day with a bottle of schnapps."
"And with that deep cough," the doctor continued, "you probably are a
smoker."
"You bet," said Goldberg, "Three packs a day for me."
"Look Mr. Goldberg," the doctor said. "You are not a healthy man. You are going to have to give up smoking and drinking right away, and that is an order. Now, before you go, that'll be $50 for my advice."
Goldberg replies, "So who's taking it?"
