Three sisters, ages 92, 94 and 96, live in a house together.

One night the 96-year-old draws a bath.

She puts her foot in and pauses.

She yells to the other sisters,

‘Was I getting in or out of the bath?’

The 94-year-old yells back,

‘I don’t know. I’ll come up and see.’

She starts up the stairs and pauses

‘Was I going up the stairs or down?’

The 92-year-old was sitting at the kitchen table having tea listening to her sisters, she shakes her head and says,

‘I sure hope I never get that forgetful, knock on wood…’

She then yells,

‘I’ll come up and help both of you as soon as I see who’s at the door.’
