There was a little old lady in a nursing home and she went into Mr. Doe's room one day and told him, she could tell him his age exactly just by looking at his p***s. He didn't believe her, but decided to go along with it anyway.

Dropping his pants "OK". "You are 96 years old" states the lil old lady.

"wow, how did you do that?" the lil ol lady walking out of the room says..."you told me yesterday".
