Worst Survivor Twist/Challenge Ideas

[Crazy]

Rock, Paper, Scissors Survivor - everyone is either a Rock or a Paper or a Scissors. This determines who beats whom in the finals. If two of the same make it to the F2, then there is a jury vote. If they are different, then it depends entirely on what their role was.

Also, if it is completely impossible for someone to win due to this (e.g. 3 Rocks and 1 Scissors in the F4), then they are just eliminated automatically.

I have a few more terrible ideas, but I am debating making a terrible Survivor game in the distant future.
