Urinal cake breakfast

There was a kid at my primary school who ate the urinal cake things because he thought they were marshmallows.
100% lies but we don't care. Have YOU ever eaten a piss cube? What do they taste like and did you suck it to make it last or crunch it?

I snuck into the older boys' toilets halfway through my first year at primary school and one of the things I did while I was in there was eat a urinal cake. Not because I thought it was a marshmallow, but because I thought that eating it would grant me the strength of all the older boys who had pissed in the urinal. This, I reasoned,would make me a superhero and bestow upon me the power to destroy all my enemies.
