Three elderly sisters, ages 92, 94 and 96, shared a house together. One evening, the 96 year old sister went upstairs to take a bath. As she put her foot into the tub, she paused. Then she yelled down to the other two sisters and asked, "Was I getting in the tub or out?"

"You dern fool," said the 94 year old. "I'll come up and see." When she got half way up the stairs she paused. "Was I going up the stairs or down?"

The 92 year old sister was sitting at the kitchen table drinking a cup of tea and thought, "I hope I never get that forgetful, knock on wood." She shook her head and called out, "I'll be up to help you both as soon as I see who's at the door."
