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 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."
