I read an article once on rejected reality tv shows, HILARIOUS!! One was called Monkey on my Back and it was like Amazing Race, only you had to do all the things with a monkey on your back... haha
My friend came up with one called The Host, like The Bachelor, only the Bachleor was a ringer for the Host, who would get to see the girls "true colors"... pretty good I thought, especially given how stale that show got.
