Three elderly men visit the doctor for a memory test.
The doctor asks the first man, “What’s two times two?”
“184,” he replies.
Turning to the second man, the doctor asks, “Your turn. What’s two times two?”
“Friday,” answers the second man confidently.
Finally, the doctor asks the third man, “Alright, what’s two times two?”
“Four,” says the third man.
“Excellent!” says the doctor. “How did you figure that out?”
“Easy,” replies the third man. “I just subtracted 184 from Friday.”
