If you sat through all the credits for 'Thor' this weekend, you saw a teaser for the upcoming Marvel superhero combo flick, 'The Avengers.'

You may have also noticed an odd credit: A "thank you" for Ralph Macchio.

What does the original 'Karate Kid' and current 'Dancing With the Stars' contestant have to do with the mighty God of Thunder? Or the superhero universe in general?

While you ponder that he was perhaps teaching Thor some karate moves or coaching Loki in what it feels like to be an 'Outsider,' the answer is much simpler.
