Frankly, we’ve no idea what makes pitch invaders tick. Booze? Too much Red Bull? A burning desire to be wrestled to the floor by a flying steward?
Because, invariably, the aforementioned situation is habitually how it all ends for the poor soul found wandering onto a field of play for their five minutes of fame – and like footage of a purse snatcher being rugby tackled by a have-a-go-hero on CCTV, there are few sweeter sights than these morons getting their comeuppance.
If you agree with you, this excellent super-cut of fans getting brought back down to earth is essential viewing, giving us bit hit after big hit throughout years of impromptu trespassers in sport.
And if you're gleefully enjoying the footage, ensure you also check out our list on sport's most memorable pitch invaders.
We bet some NFL teams could learn from it, too.
