Not many people know this, but PZ Myers, when he was a little kid, made an appearance on Mr. Science (actually, PZ mentions this often in public lectures as a reason he got into science, but I’ve never noticed him say anything about this on his blog). This was the first episode ever made, but it was never shown for some reason. This episode was made with an actor who preceded the better known Mr. Science. Apparently the actor in this video made only this one episode, I’m not sure why. Anyway, enjoy!
