Should I get a ferret? (or two)

I've always wanted a ferret but a few years ago my mom told me that the chances of me getting one were very slim. I got a ball python instead.
I also live with a 2 year old yellow Lab.

I'm 15 and I've recently decided to try, once more, to get one. I doubt my mom would let it roam around the house, but I imagine I'd let it run around in my room (which I constantly keep clean and dog-proofed) every day. I have enough money to care for it, and my parents would surely pay for the medical costs.

I'm still in school, of course, and I have an active social life, but I'm sure I can play around with it at least once a day.

My question, i suppose, would be "Should I get a ferret?". Or, possibly two, in case I'm not able to play with them more than once a day?

Thanks. :)
