The seat cuts off circulation to the legs, then op has to crawl off the shit filled toilet bowl. Just my guess.

You get up from the toilet, clean up, flush and go to the sink. Your legs are starting to wake back up, they feel like static, can’t move them. You notice the toilet is over filling, it’s clogged. You need to get to the plunger, before poop water hits the floor. Every step you take is like a new type of torture. Static shooting up from your feet, and echoing up your legs. It’s a battle you must win, but you don’t know if you can get there in time. You grab the plunger, and flight the toilet. Static shooting up, worse than before, and with every plunge. You can’t take it any more, but you know that you must. For restroom, and for country. When it’s all done, and the toilet water retreats down the drain. You legs wake up fully, and you walk away like it never happened.
