Three sisters, ages 92, 94 and 96 live in a house together. One night the 96-year-old draws water for 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 dont know. Ill 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 a cup of 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: "Ill come up and help both of you as soon as I see whos at the door."
