Crow T. Robot is one of two robotic co-hosts built by Joel Robinson to help him stave off insanity while forced to watch terrible films by the Mads on Mystery Science Theater 3000. He is the most easy-going and naive of Joel's robot companions, yet somehow, during the movies, he's always the one to deliver the most sarcastic remarks. He was originally portrayed by Trace Beaulieu, but was later replaced by Bill Corbett.
