An old couple were having problems remembering things, so they went to their doctor to find out what was wrong with them.

The doctor examined them and said that they were physically fine but might want to start writing things down and make notes to help them remember things. The couple thanked the doctor and left.

Later that night while watching TV, the old man got up from his chair and his wife asked, "Where are you going?" He replied, "To the kitchen". She asked, "Will you get me a bowl of ice cream?" He replied, "OK". She then asked him, "Shouldn't you write it down so you can remember it?" He said, "No, I can remember that." She then said, "Well I would also like some strawberries with it. You better write that down because I know you'll forget that." He said, "No, I can remember that, you want a bowl of ice cream with strawberries." She continued, "Well, I would also like whipped cream on top. I know you'll forget that so you better write it down." Irritably, he said, "I don't need to write it down I can remember that.". Then he stomped off to the kitchen. Fifteen minutes later he returned and gave her a plateful of eggs and bacon. She stared at the plate annoyed and said, "You forgot my toast."
