On the contrary!  We *do* want to answer.  Prizes are awarded based on 
the most outlandish yet correct answer, on the most literal answer, and 
on the funniest answer!

Ridiculous questions like yours are what make the daily checking of the 
mailing list worth while.

Now, if you have a _real_ question, that's not homework, check out

Happy Coding!
