Three old men are talking about their aches, pains and bodily functions.
One seventy year old man says, 'I have this problem. I wake up every morning at seven and it takes me twenty minutes to pee.'
An eighty 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 ninety year old man says, 'At seven I pee like a horse, at eight I crap like a cow.' 'So what's your problem?' asked the others.
'I don't wake up until nine.'
