Forum:Trying to ID this TOS character/episode

This frame (unknown character) sometimes shows up in the closing credits. I have always wondered what episode that it was from, and who it was/what character it was.

I just found a better, longer example in this youtube video (1:02 into the video) http://www.youtube.com/watch?v=JZAkGfJY05k

In the video clip it is clear that it is an actor removing his prosthetic makeup after a scene. You get a pretty good look at the actor's head from several angles and I still can't figure out what character this was.

Thanks, You are absolutely correct. The interview picture of him from 2007 he looks exactly like that! I have been trying to figure that out for years.
