Three sisters, ages 92, 94, and 96, live together. One night the 96-year-0ld draws a bath. She puts one foot in and pauses. "Was I getting in the tub or out?" she yells.
The 94-year-old hollers back, "I don't know, I'll come up to see." She starts up the stairs and stops. She shouts, "Was I going up or going 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", and knocks on wood for good measure. Then she yells, "I'll come up and help both of you as soon as I see who's at the door."
