Three old men were sitting around and talking.  The 80 year-old
said, "The best thing that could happen to me would just to be
able to have a good pee.  I stand there for twenty minutes, and
it dribbles and hurts.  I have to go over and over again."

The 85 year-old said, "The best thing that could happen to me is
if I could have one good bowel movement.  I take every kind of
laxative I can get my hands on and it's still a problem."

Then the 90 year-old said, "That's not my problem.  Every morning
at 6:00 am sharp, I have a good long pee.  At 6:30 am sharp I have
a great bowel movement.  The best thing that could happen to me
would be if I could wake up before 7:00 am."
