I always thought the show Fun House (from about 20 years ago) was a great idea for a show. I always dreamed about going through the obstacles on the show. Here’s the basic explanation about how it worked from Wikipedia:

Two teams (Red Team and Gold Team) of two children (a boy and a girl) played messy games and answered questions to win a chance to run through an obstacle-strewn Fun House at the end of the show.

This might seem a little juvenile nowadays (maybe) and would line lawyers up around the block, but I always thought the premise and the execution was on point.
