Last summer I was on vacation at the Beach, and bought a ton of fireworks. Let me preface this by saying over the last year i've exploded hundred of firecrackers in my toilets at my college house and never had any damage whatsoever. Now I dropped just one identical firecracker in the hotel toilet, and boom, a chunk of porcelin the size of my hand blows out the side of the toilet and water floods the whole bathroom.
I turned off the water to the toilet headed to the nearest Home Depot, bought some marine boat sealant and a chalk gun, gave it a quick fix, and they never noticed. Im sure about a month or two later the sealant degraded and it flooded again, but they never sent me any bills so I guess I won.
