Slim Goodbody ("the Superhero of Health", also known as Mr. Goodbody) is a fictional character created and performed by John Burstein. Burstein performs wearing a flesh-colored unitard with various tissues, organs and organ systems painted on the front in biologically-accurate locations and sizes. Burstein created the character in 1975. Each costume costs $4,000.
Slim Goodbody eventually received his own television series in 1980, Inside Story on PBS. The program mainly consisted of Burstein's live-show Slim Goodbody sketches, though other children's show celebrities such as Captain Kangaroo would sometimes make guest appearances. The show soon became the station's second-highest rated program, and Burstein landed roles on other stations, including Nickelodeon. Since then, Slim Goodbody has featured in several other series, as well. At one point Slim Goodbody began making educational shorts on such subjects as the fear of visiting a hospital, amongst others. One of these shorts featured Burstein's son, Devin, as a child learning about hospitals as he overcomes his fears of an upcoming operation.
Today, Burstein tours the United States and Canada dressed as Slim Goodbody and performing in Bodyology. School-based shows, performed by other actors, include Musical Health Show and Lighten Up!
