Worst/funniest one I had was an Indian student who'd flooded his bedroom in a student accommodation, I went to see him, wouldn't let me in. I could see the floor was flooded, bed sheets in the water, suitcase, clothes, fucking shambles. Eventually he let me in and I asked what had happened? (this boys padding about in his bare feet up to his ancles in sewage) he says the night before the shower got blocked and over flowed so he tried to mop it up with toilet roll and stuck all the paper down the pan and blocked the toilet. No problem I thought so I lifted the lid on the pan and it was stuffed to the rim with toilet paper, but the dirty bastard had taken the world's biggest shit on top of it all, coiled up like an anaconda!
I went fuckin mental and the boy claimed it wasn't him, someone broke into his flat and dropped the monster turd!
