Soccer referee Rodrigo Nunes de Sá may make many bad calls in his career, but none of them will be as horrible as this one. After Operario defenseman George received a red card, he got in the ref's face to dispute the call and a couple of seconds after the slightest of headbutts, Nunes de Sá decides to flop on the ground in epic fashion. Now that was a pretty bad acting job. But is it really worst than the people on this list? [via The Big Lead]
