Comedy Central hosts and friendly rivals Jon Stewart and Stephen Colbert just corpsed their way through a battle of Star Wars trivia—and lightsabers—to determine which of them is a bigger nerd.

In real life, it's probably Colbert, but in the Comedy Central Expanded Universe, Stewart takes it because he's more willing to cosplay. (And why not? The man has his own official Stormtrooper action figure, given to him by George Lucas.)

As much as I'd love to imagine that this is what Stewart and Colbert always do with their free time, there's a point to it: They're promoting UNICEF through the Star Wars charity campaign that J.J. Abrams launched a while back. If you're still hoping to win that Episode VII cameo, there are 8 days left.
