You'd think that's a thing but with all the fatasses we have in this country there's a whole industry out there catering to them.
The thing that just made me shake my head was this:
The Shit Stick or "toilet paper wand" I believe is the proper term.
You affix toilet paper to it and use it to wipe your ass. The button on the end is to open it up so you never touch the dirty paper.
When you need this to clean after taking a dump you're too fucking fat. And yet this has been selling... since the 90's I believe. Seat belt extenders are just the next logical step when you've given up on life. The next step after that? A smaller steering wheel so it doesn't dig into your gut.
