The thing that always bugged me about Golden Balls (aside from the terrible name) was the way stealers would act like it was just a game when they had in fact taken thousands of pounds from another person through deception. Certainly it was legal and even encouraged by the format of the show but it was never the right thing to do.
I've seen people immediately regret doing it when they see that their opponent shared. They seem more upset about it than the loser and tend to cite an expectation that the other person would steal as their reason for stealing, even though this makes no logical sense. It was a fascinating but horrible ending to sixty minutes of otherwise tedious viewing.
