Thanks A Lot, Deb!

So my cousin Deb sends me this math problem:

This is not a trick question - just a straightforward math problem. This is a real math problem so don't say that a bus has no legs (and there is no driver).

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?

That's a damn lot of cats, that's all I have to say.

So, who can get the right answer...without Googling it? C'mon! Stretch that brain you haven't used for a math problem in 20 years! You can do it! I'll admit that I'm really out of practice 'cause it took me an embarrassing number of tries to get it right. I always did suck at math.
