Three sisters aged 92, 94 and 96 shared a house. One evening the 96 year old decided to take a bath. After the bath was drawn she put in one foot and stopped. She yelled out, "Was I getting into or out of the tub?"
Her 94 year old sister yelled back, "I don't know, I'll come and check." Half way up the stairs she stopped to yell, "Was I gong up or down the stairs?"
The 92 year old sister sitting at the table in the kitchen was having a cup of tea. She shook her head and said, "I hope I'll never get as forgetful as those two." And knocked on the wooden table for extra good measure. Then she yelled to her sisters, "I'll be up to help both of you as soon as I see who is at the door."
