The Sci-Fi channel did a reality show last year that I actually enjoyed watching. It is called "Who Wants To Be A Superhero".
Average people (most of them trying to be actors I would guess) tried to prove to superhero creating legend Stan Lee that they were the best Superhero for him to make a comic about.
They ran through a bunch of trials and competitions and some of it was actually quite funny and entertaining.
The second season of the show will debut on July 25th. The offical site has some audition videos for Season Two. You have to see them to believe them.
