Good one alan. I've got one I just heard recently.

Three friends are sitting in the common room of the elderly care facility in which they reside complaining about their aging bodies. The first says,

"The first thing I do when I get up at 8 o'clock is go stand in front of the toilet, but I'm lucky if I start to pee before 8:30."

"Oh yeah?" says the second. "I get up at 9 to go sit on the pot and I'm lucky if anything happens before 10."

The third shakes his head and says, "By 10 o'clock I'm crapping like a champion and pissing like a racehorse. Only problem is I don't get up until 11."
