Those of a nervous disposition should probably avoid clicking Play because this video does not end well. It’s funny throughout, right up until those last few seconds. And then it turns bad.
This must be at a music festival or some other public gathering where people are drinking lots and peeing more. Hence the rows of portaloos.
One guy decides to climb atop the portaloos even though he is clearly inebriated. After almost falling through several of them, and then getting pelted with cups and bottles, he attempts a highly improbably leap to the next set.
He fails, obviously, and ends up landing on his head. What’s scary, and what stopped me laughing instantly, is the fear that he could be seriously injured. Let’s just hope he lived to tell the tale of the day he got drunk and ran on top of some urinals.
