Three old ladies were sitting at the dinner table

Three old ladies were sitting at the dinner table discussing their problems with getting old.

The first one said, “Sometimes I catch myself with a jar of mayonnaise in my hand while standing in front of the refrigerator, and I can’t remember whether I need to put it away, or start making a sandwich”.

The second lady says, “Yes, sometimes I find myself on the landing of the stairs and can’t remember whether I was on my way up or on my way down”.

The third one says, “Well, ladies, I’m glad I don’t have any of those problems, knock on wood”.

As she hit her knuckles on the table she looked up and said,

“That must be the door… I’ll get it!”
