Dr. Teeth and The Electric Mayhem his few speaking appearances was in the Shirley Bassey episode where he sang a line of "Barnyard Boogie." He was mainly created so that Whitmire could have a character to perform in the band. His lack of character development was apparently due to Whitmire's uncertainty about performing Lips. He was less experienced as a puppeteer at the time and wanted to use a voice like Louis Armstrong but was afraid of offending African Americans. After "The Muppet Christmas Carol", he wasn't seen at all until the NBC special "Christmas in Rockefeller Center". He also appeared in the movie "The Muppets".
