Friday Fun

Dear Diary,

UPDATE: May 23, 2008 at 9:45 AM I solved the problem.  I signed my name on the list.

My Friday fun might turn into rage if I don't solve this word problem.  So far I'm stuggling with this one.  If you figure out the answer let me know.  Don't tell me the answer just rub it in my face that you got it sooner than I did.

Word Problem:
If you can open the spreadsheet, you'll see it's a very small list of people who have gotten the correct number -- but the list is getting longer.

There are 7 girls in a bus.
Each girl has 7 backpacks.
In each backpack, there are 7 big cats.
For every big cat there are 7 little cats.

Question: How many legs are there in the bus?

The number of legs is the password to unlock the Excel sheet.  If you open it, add your name and send it on to see who else can unlock it.
