The way I see it, the homeowner opened up their home and never expected that a guest would obliterate their toilet and then leave it for the next party goer to fix. So the homeowner is an innocent party. I say go back to the house, swab the plunger to get some DNA. Test the DNA to identify who the person was that clogged the toilet. They should be the ones to pay not only for your dry cleaning bill, but also for a half hour of labor. Plugging someone else's crapper and leaving it is just not right!
