Not only did he import lions, sumo wrestlers, and heavyweight boxers to the White House, but he also had a huge history of bad-assery. This includes, but is not limited to: being a golden glove boxer, undergoing surgery without anesthetic and while fully conscious, mugging a horse, patrolling the streets of New York by himself, kicking ass and taking names.
Yeah, dude. You don't mess with Teddy!Getting shot at point blank range, surviving and immediately giving a 90 minute speech right after too!
