As a reply, I am a huge Fun House fan, and it definitly was not Tiny. Typically Tiny would be seen during the intros and during this intro JD came out by himself. I can say despite what Matt's page says, it wasnt Tiny.
As to the game, there were 4 stunts instead of the standard 3, and the scoring was quite bizarre. Instead of awarding the usual points for winning the stunt, they awarded a dollar for each thing. For example stunt one was bobbing for bagels, and the red team won 3-2. So, after the 25 point question following the stunt, the score was 28-2.
The stunts were similar to your standard FH stunts with the possible exception of one stunt where they put together large blocks to make faces of celebs.
The Grand Prix Race followed and was much the same. Then they went to the Fun House. This was the big difference, as since it was a pilot, the prizes were incredible. Plus getting the power prize meant you automatically won all the prizes. Also the cash tags didnt count toward the limit of tags the players grabbed.
Also of note, JD scanned the tags via a bar code, which IMO was really neat. One of the contestants was Douglas Emerson (of early 90210 fame) who went on to compete on FH as a celeb the following year.
