Taylor Lautner, who will play Jacob Black in New Moon, was in an episode of My Own Worst Enemy that first aired November 10, 2008. He played the son of the main character, who was played by Christian Slater.

The show was cancelled after nine episodes, but we wanted to bring you this clip of Lautner kicking butt while taking part in some extracurricular activities his parents didn’t know about.

And, in case you haven’t’ seen it–a much younger Lautner doing martial arts on ESPN in 2003.
