The latest episode was them redoing some of the experiments and this time they painted the goofy sidekick type guy (sorry can't remember the names Adam maybe ?).

AH! Cool, that one. That one's on the Tivo and I haven't watched it yet. I didn't read the description closely enough and thought it was perhaps a re-hash compilation episode like when they re-aired all of the "best animal myths" in one episode. So I wasn't in any hurry to watch it. Now that I know it's a new episode, I'll be sure to watch it.
