Dave went to see the doctor one day and said, "You've got to help me. I need something so that I can get it up for my wife." The doctor consulted his medical books, then gave Dave a pill to swallow Unfortunately, Dave's wife wasn't home when he got there. Needing relief he had to masturbate.
The next day, the doctor called and heard the story. He said, "Sol, you didn't have to beat off. There are other women around." Dave said, "For other women, I don't need a pill."
