A man 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 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 right arm in a sling.
The doctor asked,
"What happened to you?"
The man said,
"No one showed up."
