Mad Mad House is a 2004 reality television series about a group of ten contestants competing for $100,000. The contestants lived together in a house inhabited by another group of people known as the alts (for their alternative lifestyles). The alts voted the contestants off by judging them on their ability to perform "challenges," which were based loosely on the practices of each alt's lifestyle, and their behavior and attitude with the other guests. The show aired on the Sci Fi Channel in the United States and on Space in Canada. Reruns have also been aired on Fox Reality Network.
