Two old ladies
Two old ladies met in the supermarket, one says to the other;
"Hey, Gladys, have you noticed as you get older your fanny gets bigger?".
"No, Dorothy, can't say as I have, how can you tell?"
"Put a mirror on the floor and have a quick squint"
The old dear goes home, nips upstairs, takes the mirror off the wall, puts it on the floor, slips off her undies and has a quick look.
Just at that her husband passes the bathroom door, does a double take, runs into the bathroom and pushes the old girl. She falls into the bath, hurts her arm, pulls down the shelf and gets covered in all sorts of bubble bath, talc and the like.
"You bas***d, Jimmy, I've hurt my arm and look at the state of me"
Jimmy says, "You ungrateful old cow, if you'd have fallen down that hole you'd have broken your bloody neck"
