There are three old sisters living in a house
together. The first sister is pouring the water for her bath. She puts one foot in and asks herself if she was getting in our out. She stands there trying to figure it out. The second sister is walking up the stairs. She gets to the middle and can’t remember if she was going up or down. The third sister seeing all of this stands next to the cubboard and says, ‘I hope I never get as bad as those two. Knock on wood.’
‘Who’s there?’
