We've all been there. We've seen it, maybe even been directly involved. Sometimes a call made by a referee or official merits a "discussion."

Serbian tennis player Viktor Troicki thought Cedric Mourier needed one after the chair umpire overuled Troicki's backhand in a match at the Italian Open.

Troicki passionately disagreed with the call, so much so that he recruited the help of a cameraman to prove the error of Mourier's ways.

While such theatrical protests are far from the norm, it does show how passionately Troicki felt about his "life" in the tournament, one that later ended despite his best efforts both during and away from live play.
