Joseph and the Amazing Technicolor Dreamcoat

Possibly the worst musical ever. Written by the idiot composer Andrew Lloyd Webber, it's the retelling of the Bible story of Joseph, done through silly, lighthearted songs. The Pharaoh is depicted as Elvis (???), and there is a country song, a reggae song, and a Jazz song. All of these are anachronisms, as well as being incredibly stupid and contributing nothing to the story.
