Take a manic talent show host, mix in three celeb judges (any Gabor will do), and regular appearances by an NBC stagehand who dances while getting pelted with junk - and you have the ultimate 70s televised party The Gong Show.
( The Gong Show Movie is a bore- don't bother)- stick with the original
After The Gong Show was cancelled, Eugene "gene gene" Patton remained a stagehand at NBC into the 1990s. Sadly, He lost both legs to complications from diabetes in 2001.
Gene had a cameo as himself in the film Confessions of a Dangerous Mind.
