Have you ever seen the movie "Spaceballs" ? It's a spoof of Star Wars by Mel Brooks (that should say it all) starring John Candy and Rick Moranis among others. I remember watching this movie with my dad as a kid...
One of the characters in it was called Lord Dark Helmet and was played by Rick Moranis.
When Christopher was learning to ride his bike, we could not find his bike helmet anywhere, so he borrowed the motorcycle helmet we had lying around the house.
We started calling him Lord Helmet after that day....
