I clogged my GF's toilet one time, and her mom was on the way home from work. I boiled a big pot of water, poured it in, and broke the shyt down (literally). My best de-clog improv.
I tried that and the toilet was still blocked but I had a lovely smell of cooked shyt that stayed in my house for several days,despite leaving windows open and spray air freshner. I couldn't invite none of my friends round or the squeeze I was seeing because otherwise they would be inhaling the contents of my guts. I stick to plungers in future.
