Just recently I managed to catch a couple of episodes where the evicted housemate was sent straight back in because of an 'error' in counting the votes. Has anything similar happened that anyone is aware of? Or that anyone is willing to mention and risk humiliation for watch the tripe that this show usually is regrded as?

TBH, I watched almost the entire first series here and thoroughly enjoyed it, but have only watched a few episodes of each successive one because they've all sucked.
