An elderly man is having trouble with his memory. Problem is, his elderly wife is, too.
They visit the doctor, who confirms that this is indeed the case, a common consequence of old age. He suggests a medication. The couple talk it over, and decide to refuse.
"We'll just pay better attention," the husband says. "We'll try harder. We'll remember if we just put forth good, honest effort."
The next night, the man says to his wife, "I sure could go for some ice cream."
The wife replies, "I'll get it for you. Would you like strawberries with that?"
"Yes, I would, thank you. Do you think you can remember that?"
"Oh yes. Ice cream and strawberries. How about some hot fudge?"
"That sounds delightful. That's three things now. Can you remember?"
"Of course! Ice cream, strawberries, and hot fudge. Whipped cream?"
"Yes, thank you."
"Ice cream, strawberries, hot fudge and whipped cream. Got it."
Twenty minutes later, the wife emerges from the kitchen. She hands her husband a plate.
On the plate are fried eggs, grits, and toast.
The husband yells, "Gosh darnit, woman, you forgot the bacon!"
