The Memory Test

Three elderly men were at the doctor for a memory test. The doctor asked the first man, "What is three times three?" "274," was his reply.

The doctor said to the second man, "It's your turn. What is three times three?" "Tuesday", he replied.

Then the doctor asked the third man, "Okay, your turn. What's three times three"? "Nine", he answered.

"That's great!" said the doctor. "How did you get that answer?”

"Easy," said the third man. "I subtracted 274 from Tuesday."
