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 is 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."
