What should I get painted on the back of my leather jacket?

It's a mud brown A2 bomber jacket, so it's for like a pilot, not a biker. I'm gonna take helicopter lessons in a few years, but now I'm a year or two underage. I'm thinking of some animal that would look cool, with some message above it. I don't want anything dorky, since I'm not actually an acomplished pilot yet. Any ideas that if you saw a Highschool junior wearing a leather jacket casually, you'd think it'd look cool? Like I said, MAYBE animals, tigers, eagles, panthers, snakes, etc.
