A Memory Joke

A couple in their nineties are both having
problems remembering things.
During a checkup, the doctor tells them 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?"

"Sure."

"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?"

He says, "I can remember that. You want a bowl of
ice cream with
strawberries."

"I'd also like whipped cream. I'm certain you'll
forget that, write it
down?" she asks.

Irritated, he says, "I don't need to write it
down, I can remember it!
Ice cream with strawberries and whipped cream - I
got it, for goodness
sake!"

Then he toddles into 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, then says,
"Where's my toast ?"
