Steve singlehandedly taking back his ship armed with one pistol, scaring off all the heavily armed pirates by himself in his bathrobe and speedo. Then calling them all amateurs after he finds they left their dog in the rush to get as far away from him as possible.
And then he storms their home base to rescue Hennesey, using copious amounts of dynamite. He blows up their boat, the hotel they were squatting in, get in a shootout, and get out scot-free. Steve has his faults, but he can be an undeniable bad ass when he needs to be. Accompanied by a Crowning Music of Awesome as well.
