A friend of mine sent me this little quiz by the email. I've got no idea where the idea came from but it is clever none the less.
"Subject: CHOCOLATE MATHEMATICS
DON'T CHEAT BY SCROLLING DOWN FIRST!
It takes less than a minute.......
Work this out as you read.
Be sure you don't read the bottom until you've worked
it out! This is not one of those waste of time things,
it's fun.
1. First of all, pick the number of times a week that
you would like to have chocolate. (try for more than
once but less than 10)
2. Multiply this number by 2 (Just to be bold)
3.. Add 5. (for Sunday)
4. Multiply it by 50 I'll wait while you get the
calculator................
5. If you have already had your birthday this year
add 1754.... If you haven't, add 1753 ......
6. Now subtract the four digit year that you were
born.
You should have a three digit number .
The first digit of this was your original number
(i.e., how many times you want to have chocolate each
week).
The next two numbers are .......
YOUR AGE! ~ ( Oh YES, it IS!!!!! )
THIS IS THE ONLY YEAR IT WILL EVER WORK, SO
SPREAD IT AROUND WHILE IT LASTS"
Edit for 2005: Now that it is 2005 the above calcutions do not give the right answer. If you change step 5 to: "If you have already had your birthday this year add 1755.... If you haven't, add 1754" it works correctly.
