Three old ladies are sitting in a diner, chatting about various things.One lady says, You know, Im getting really forgetful. This morning, I was standing at the top of the stairs, and I couldnt remember whether I had justcome up or was about to go down.

The second lady says, You think thats bad? The other day, I was sitting on the edge of my bed, and I couldnt remember whether I was going to bed or had just woken up!

The third lady smiles smugly. Well, my memorys just as good as itsalways been, knock wood. She raps the table. With a startled look on her face, she asks, Whos there?
