Memory Test

Three elderly men visited the doctor for a memory test. The doctor asked the first one, "What's three times three?" "285!" the man replied. Worried, the doctor turned to the second man. "How about you? What's three times three?" "Uh, Monday!" the second man shouted. Even more concerned, the doctor motioned to the third man. "Well, what do you say? What's three times three?" "Nine!" the third man replied. "Excellent!" the doctor exclaimed. "How did you get that?" "Oh, it's pretty simple," the man explained. "You just subtract the 285 from Monday!"
