Tony Danza may not be the first actor to come to mind when you’re picturing badasses, but the guy was a pretty good professional boxer, garnering a 9-3 win-loss record with all of his victories ending via knockout. In this bout, “Tough” Tony Danza knocks out his opponent in only 44 seconds. Tony might have built up a successful career for himself, but after a casting director saw him working out in a gymnasium and thought he’d be good for a role on Taxi, acting became his full-time gig.
