A man went to the doctor’s office to get a double dose of Viagra. The doctor told him that he couldn’t allow him a double dose. “Why not?” asked the man. “Because it’s not safe,” replied the doctor. “But I need it really bad,” said the man. “Well, why do you need it so badly?” asked the doctor. The man said, “My girlfriend is coming into town on Friday; my ex-wife will be here on Saturday; and my wife is coming home on Sunday. Can’t you see? I must have a double dose.” The doctor finally relented saying, “Okay, I’ll give it to you, but you have to come in on Monday morning so that I can check you to see if there are any side effects.” On Monday, the man dragged himself in; his arm in a sling. The doctor asked, “What happened to you?” The man said, “No one showed up.”
