Jokes to brighten your day

Aunt Mary and two of her old friends were having a glass of lemonade at her house, and talking about their health problems. "I think I must be getting old." said one of the women. "I sometimes find myself at the foot of the stairs, and I can't remember if I was going up to get something, or coming back down." "I know what you mean," added the second friend. "Sometimes I'll be standing in front of the refrigerator, and I can't remember if I wanted to take something out, or if I had just put something in." Aunt Mary sat up. "I guess I'm better off than either of you. I haven't had any problems like that so far, knock on wood". Saying that, she rapped on the table three times. She looked at the other two women and stood up. "Excuse me," she said, "Someone's at the door."
