Got this in an email the other day:

ARE YOU SMARTER THAN A 5TH GRADER?

There are 7 girls on 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.

I've figured left & right, up and down and haven't got the right answer yet.
