During a check-up, the doctor tells a forgetful couple that they're physically okay, but they might want to start writing things down to help them remember.
Later that night, while watching TV, the old man gets up from his chair.
"Want anything while I'm in the kitchen?" he asks."Will you get me a bowl of ice cream ?"
"Don't you think you should write it down so you can remember it ?" she asks.
"No, I can remember it."
"Well, I'd like some strawberries on top too. Maybe you should write it down, so as not to forget it ?"
Irritated, he says, "I don't need to write it down. I can remember that. You want a bowl of ice cream with strawberries."
Then he toddles to the kitchen.
After about 20 minutes, the old man returns from the kitchen and hands his wife a plate of bacon and eggs.
She stares at the plate for a moment.
"Where's my toast?"
i would guess the end of it!
