We've heard of disgruntled spectators hurling objects like lemons and banana peels at performers and athletes to express their disapproval over an unworthy performance.
But throwing fish at an athlete?
Now that's a first–at least one that was archived on social media.
A viral video showed an Argentinian soccer player being slapped in the face by an airborne amphibian thrown by a fan during a Primera Division match in Buenos Aires between Independiente and Racing Club.
Independiente forward Leandro Fernandez was seen taking a stumble to the ground as a result of the impact after Monday's scaly encounter.
Medics tended to him and the fallen player appeared to be okay as he returned to complete the match.
Unfortunately, his team eventually lost to the rival team, Racing Club.
Amateur comedians on Twitter seized the opportunity for jokes.
While the fish tosser was not identified and their harmful actions are not to be encouraged, their audaciousness of lugging a fish into the venue for the purpose of hurling it at a player with impressive accuracy cannot be ignored.
