"Sixty is the worst age to be," said the 60-year-old man. "You always feel like you have to pee and most of the time you stand there and nothing comes out."
"Ah, that's nothin," said the 70-year-old. "When you're seventy, you don't have a bowel movement any more. You take laxatives, eat bran, sit on the toilet all day and nothin' comes out!"
"Actually," said the 80-year -old, "Eighty is the worst age of all."
"Do you have trouble peeing, too?" asked the 60-year old.
"No, I pee every morning at 6:00. I pee like a racehorse on a flat rock; no problem at all."
"So, do you have a problem with your bowel movement?"
"No, I have one every morning at 6:30."
Exasperated, the 60-year-old said, "You pee every morning at 6:00 and crap every morning at 6:30. So what's so bad about being 80?"
"I don't wake up until 7:00."
