An 80-year-old-couple are having problems remembering things, so they decide to see their doctor to find out if anything is wrong with them.
They see the doctor and explain the memory problems they've been having. After a check-up, the doctor tells them that they are physically fine but might want to start writing things down to help them remember things. They thank the doctor and leave.
Later that night while watching TV, the old man gets up from his chair.
"Where are you going?" asks his wife.
"To the kitchen," he replies.
"Will you get me a bowl of ice cream?" she asks.
"Sure," he says.
She says, "Maybe you should write it down so you'll remember."
"I'll remember," he says
"Well, I'd also like some strawberries on top," she says. "You had better write that down cause I know you'll forget."
"I can remember that," he says, as he begins to lose his patience. "You want a bowl of ice cream with strawberries."
"I'd also like whipped cream on top," she adds, "I know you'll forget that, so you'd better write it down."
Hopping mad he says, "I don't need to write that down! I'll remember just fine." He fumes into the kitchen to get the food.
After about 20 minutes he returns from the kitchen and hands her a plate of bacon and eggs. She stares at the plate for a moment and says, "You forgot my toast."
