I accidentally sit on a plastic cup without realising, it's crushed flat!
Surely my ass didn't do that? I stand on the scales and weigh myself, then sit on them with my full weight and weight my butt too.
I then decide to be destructive and see what else can take the full brunt of my behind, finding household objects and sitting on them to crush them flat with just my butt and my hands and feet off of the floor!
