Yep I'd stick with strictly corn....hey we feed it to the squirrels and I've never seen them needing any toilet paper. Swallow the corn whole....then get you one of those colon cleansers....that should do it.
Or you could have your colon spritzed....yeah, maybe that would work.....that's where they shove a water hose up your butt and rinse you out real good.
Hmm can’t help you there. But if you ever want really cool looking shits, a diet of peanuts, corn, and blue slurppies would produce something you would want to take pictures of and share with friends and family.
