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 around 6:30 am 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.
