Depends on state law. In Texas, if you can catch 'em, you can keep 'em. In other states they might be banned or require licenses. (but since they're not dangerous and are only bad carriers of one major disease, no one's likely to come and take it away unless you get a lot of complaints)
Sure, documentaries are awesome. I would gladly watch them with you- but I'd be watching movies too. ^^
Would you go out with me because I can pick things up and throw them with my feet, so dirty laundry is dealt with while standing on one leg and using the toes of my other foot to touch everything?
