If you could have any animal as a pet, what would it be?

I'd love to have a grizzly bear as a pet, so I could give it a huge bear hug. And it could tear my head off and end my misery when the time is right.
But no for real I love bears they're pretty intelligent animals and I've seen a couple videos on youtube of someone having a polar bear as a pet and its the most heartwarming thing I've ever seen. Which animal would you like to have as a pet? Nothing basic or boring, have it be something interesting!
