"Sixty is the worst age to be," says the 60-year-old, "You always feel like you have to pee. And most of the time nothing happens."
"Ah, that's nothing," says the 70-year-old. "When you're 70, you don't have a bowel movement any more. You take laxatives, eat bran, you sit on the lavatory all day and nothing happens."
"Actually," says the 80-year-old, "Eighty is the worst age of all."
"Do you have trouble peeing too?" asks the 60-year-old.
"No, I pee every morning at 6.00 am. I pee like a racehorse .... no problem at all."
"Do you have trouble having a bowel movement?"
"No, I have one every morning at 6.30 am."
Puzzled by this, the 60-yar-old says, "Let's get this straight. You pee every morning at 6.00 am and poop every morning at 630 am. So what's so tough about being 80?"
