Three sisters ages 72, 74, and 76 lived in a house together. One night the 76-year-old drew a bath. She put her foot in and paused. She yelled down the stairs was I getting into or out of the bath?The 74-year-old yelled back I dont know. Ill come up and see. She started up the stairs and paused. Then she yelled, was I going up the stairs or down?The 72-year-old sat at the kitchen table having tea, listening to her sisters. She shook her head sadly and said, I sure hope I never get that forgetful. She knocked on wood for good measure. She then yelled, Ill come up and help both of you as soon as I see whos at the door.
