Okay, hands up, who's pissed in the Olympic diving pool?
It might have been funny at school having a sly wee in the deep end, but this is the Olympic Games damn it. People are trying to do sport.
The pool appeared to be in pristine condition when Tom Daley and Daniel Goodfellow won their bronze medal in the 10m synchronised platform dive.
The pair were pictured celebrating in the azure blue water of the diving pool at the Maria Lenk Aquatics Centre.

But the scene of their bronze medal success looks a lot different now compared to the neighbouring Olympic swimming pool where Jazz Carlin took silver in the swimming yesterday.
It began turning more and more green during Tuesday night's women's 10m platform final.
Tom Daley, whose medal took Britain's tally up to four so far in Rio, stuck a picture up of the two pools side by side from the stands and we can see what he means.
He sounded pretty puzzled about why the water had turned from aqua blue to piss green...

BBC commentator Dan Walker pretty much said what everyone was thinking on Twitter...

But most of all people just genuinely felt for the Olympic divers having to throw themselves into the pissy green water below...
