A friend who was beginning to experience memory loss went to the doctor. The doctor told him he should start writing things down. One day the friend was watching TV with his wife and he said, "I think I'll go fix me a snack--you want anything?"
She said, "Yes, I'd like a bowl of ice cream, but you better write it down."
He protested that he could remember something as easy as ice cream, but she said, "But I want some whipped cream on it, so you better write it down."
"Oh, that's easy," said he, but she said, Yes, but I want a cherrie on top--you better write it down."
He went into the kitchen still claiming to be able to remember it. He was in there for a while and when he came back he presented her with a plate of bacon and eggs! She looked at him in disbelief for a moment, then said, "John, you forgetful thing! Where's my toast?!"
