Three sisters aged 92 94 and 96 who are all losing their marbles live in a house together. One night the 96 year old runs a bath, she puts her foot in and pauses, then yells to the other sisters "was i getting in the bath or out?" The 94 year old says "i'll come up and see", she starts walking up the stairs and pauses, "was i walking up the stairs or down?", she shouts. The 92 year old is sitting at the kitchen table having tea listening to her sisters, she shakes her head and "i sure hope i never get that forgetful, knock on wood" she then yells "i'll come up and help you both as soon as i've seen who's at the door!"
