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