Now, I consider myself to be a pretty gosh-darn good theatrical swordsperson. Rapier was my specialty back in my SAFD days, and I'm an okay hand at the stage katana. I am also a Star Wars Geek of the first water.
However, Ryan and Dorkman make me look like a kid playing by Boulder Creek with a stick. And I'm not ashamed to admit that. Attack of the Show (on G4) mentioned them in passing once, I went and found them on YouTube--there are two epic lightsaber fights, and mean teasing whispers of a third.
