Throughout the history of team sports, spectators have probably joked about causing bodily harm to an umpire or referee. In the wake of Barcelona's last-minute Champions League semifinal victory over Chelsea at Stamford Bridge, this sort of thinking has become no laughing matter as the match's official -- Tom Henning Ovrebo -- has been forced into hiding after receiving numerous threats. The Norwegian denied Chelsea, what the Blues felt, were three possible penalty kicks -- the first when Dani Alves dragged down Flourent Malouda in the box in the first half and the next two on possible handballs on Barcelona players Gerard Pique and Samuel Eto'o. The second call, which would have gone against Eto'o in injury time, has already sparked numerous YouTube parodies featuring Chelsea's Michael Ballack's over the top reaction.
