Some dude wearing an Australian flag jumped onstage at Eurovision and mooned everyone

Eurovision fans often complain that Australia shouldn't be included in the contest -- after all, it's not a European country. But on Saturday, the country was centre stage after a prankster interrupted the show.

Here's what went down (under). While last year's winner, Jamala, was performing her number, an enthusiastic man wearing an Australian flag somehow got himself onto the stage. He then proceeded to moon everyone. Fun!

Initially, it was thought to have been an Australian hooligan causing havoc. But it turns out, it was Ukrainian prankster Vitalii Sediuk. In not fun news, he is now detained in a Ukranian prison.

The internet, predictably, went wild following the incident. (Worth noting: many people watching Eurovision had been drinking for a while at this point.)

Man, American television suddenly seems really boring.
