Three elderly men are at the doctors office for a memory test.

The doctor asks the first man, What is three times three?



274, is his reply.



The doctor rolls his eyes and looks up at the ceiling, and says to the second man, Its your turn. What is three times three?



Tuesday, replies the second man.



The doctor shakes his head sadly, then asks the third man, Okay, your turn. Whats three times three?



Nine, says the third man.



Thats great! says the doctor. How did you get that?



Simple, he says, just subtract 274 from Tuesday.
