Is plunging a toilet without a plunger a good tip or a horrible idea?
Ok all dirty humor aside, that sounds like a terrible idea.  OMG, what a mess that could make.  First off, the idea is to never plunge the jam further down the pipe, instead the best solution is to suck the jam back up the pipe first, allow any vacuum to ease then send it down the pipe. How this is done is to submerge your plunger into the water allowing the cup to fill with water. GENTLY push it down over the drain opening slowly  forcing the water out and compressing the plunger cup. Now you will created a good seal and a vacuum. Quickly PULL the plunger out. repeat this process a few times before attempting to plunge down. The idea here is to pull the blockage back a bit and open a path.  Once you see the water receding a bit, vigorously plunge up and down. Trust me, this works in most cases and will be a lot less messy than High altitude bombing!
