Bubba went to the doctor's office to ask for a double dose of Viagra.
The doctor told him that he couldn't allow him a double dose.
"Why not?" asked Bubba..
"Because it's not safe," replied the doctor.
"But I need it really bad," said Bubba.
"Well, why do you need it so badly?" asked the doctor.
Bubba answered, "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 gotta 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 morning, Bubba dragged himself in to the doctor's office, his right arm in a sling.
The doctor asked, "What happened to you?"
Bubba said, "Nobody showed up!"
