Once upon a time there were three sisters, ages 92, 94 and 96, and they all lived together.

One night the 96 year old ran a bath. She put one foot in and paused. "Was I getting in the tub or out?" she yelled.

The 94 year old hollered back, "I don't know. I'll come and see." She started up the stairs and stopped. She shouted, "Was I going up or coming down?"

The 92 year old sitting at the kitchen table having tea, listening to her sister’s shook her head and said, "I sure hope I never get that forgetful," and knocked on wood for good measure.

Then she yelled, "I'll come up and help both of you as soon as I see who's at the door."
