An old man was going to the kitchen and offered to bring his wife some food. She said, "No, that's ok, because you'll just forget what I want." He insisted that he wouldn't forget, so she finally gave in and said, "I'd like a bowl of ice cream with two cookies. Two! Don't forget!"
So he went into the kitchen, and was in there a very long time. When he finally came back out he handed her a beautiful tray with a plate full of scrambled eggs and bacon. She gaped at the food in astonishment, and blurted out, "See? I told you you wouldn't remember what I asked for! Where's my toast?"
