Three ladies were discussing the travails of getting older. One said, Sometimes I catch myself with a jar of mayonnaise in my hand, while standing in front of the refrigerator, and I cant remember whether I need to put it away, or start making a sandwich. The second lady chimed in with, Yes, sometimes I find myself on the landing of the stairs and cant remember whether I was on my way up or on my way down. The third one responded, Well, ladies, Im glad I dont have that problem. Knock on wood, as she rapped her knuckles on the table, and then said, That must be the door, Ill get it!
