I think CBS made a mistake in not specifying this task as a Detour on-air. Some of the racers were clearly not comfortable with the skimpy outfits, and if the viewers were under the impression that the contestants basically had no choice but to go through with the task, it could put the show in a bad light. But if everyone knew that teams had been offered another option, it would seem less like they were 'forced' into it.
In fact, I'm surprised that everyone chose this side of the Detour. Do we have any idea what the other was?
