Can anyone remember a show in the 80's where a guy wore an skinsuit with a depiction of the digestive track on it? I think Richard Simmons was the host of this health show, mabey. If so can you also provide info on where I could see some pictures or vedio of it? Thank you

You posted a while back, so you may not need this anymore, but you are thinking of Slim Goodbody. He did look a lot like Richard Simmons, but it was a different guy. He's on YouTube:
