Ancient Gravestone Protests Blown Call

Proof that people have been complaining about referees for thousands of years:

The tombstone was donated to the Musee du Cinquanternaire in Brussels, Belgium, shortly before World War I. It shows an image of a gladiator holding what appear to be two swords, standing above his opponent who is signalling his surrender. The inscription says that the stone marks the spot where a man named Diodorus is buried."After breaking my opponent Demetrius I did not kill him immediately," reads the epitaph. "Fate and the cunning treachery of the summa rudis killed me." The summa rudis is a referee, who may have had past experience as a gladiator.
