One very disturbing episode is when people in pigeon costumes take the top off their costumes. They green screen it to makes the heads disspaear and put red lines, pretending to have their heads cut off. Henson says "oh, Johnny, pigeons are such horrible creatures"!
Nothing frightening, just much action with players going through obstacle courses. If they fall, many injurys occur. But they always end up being fine.
In an episode, a woman flings in the sky and violently falls into water. Sound effects are added and is the most violent in the series.
