Three Elderly Sisters live in a huge two story house. Martha is upstairs and is going to take a bath. She yells down and asks, "Dorthy, was I getting in the tub or out?"

Dorthy replies, "You were getting in the tub!"

The second old lady walks up to the foyer stairway and stops. She looks up and then she says, "Dorthy, was I going upstairs or just coming down?"

Dorthy replies, "Mary, you were going up stair!" After a slight pause, Dorthy continues, "God Help me." She then knocks on the table twice with her fist and then says, "Was that the front door or back?"
