Dean Kamen showed up on The Colbert Report last night to show off Luke -- the advanced prosthetic arm he's been working on with DARPA and the Defense Department for the past few years.

Just more proof that Colbert is a major gadget nerd. The video's after the break -- hit the read link if you want to watch the entire episode.
