Memories

Three men, all in their mid-90's, are being visited at the home by a doctor who is administering memory tests.

The doctor says to the first man, "What is three times three?"

"274" was his reply.

The doctor says to the second man, "It's your turn. What is three times three?"

"Tuesday" replies the second man.

Disheartend, the doctor turned to the third man, "Okay, your turn. What's three times three"?

"Nine" says the third man.

"That's great!" says the doctor, glad that at least there is one with a clear mind. "And how did you get that?"

"Simple," says the third man. "I subtracted 274 from Tuesday"
