Three old men are talking about their aches, pains and bodily functions.
The 70 year old man says, "I have this problem. I wake up every morning at seven and it takes me twenty minutes to pee."
The 80 year old man says, "My case is worse. I get up at eight and I sit there and grunt and groan for half an hour before I finally have a bowel movement."
The 90 year old man says, "At seven I pee like a horse, and at eight I crap like a cow."
So what's your problem?" ask the others.
"I don't wake up until nine!"
