As per the request of one of my dear friends on sst(Not naming anyone) I've went up to my kitchen and decided to shove a potato up my ass.
Unfortunatelly, to my own dismay, it did not fit through. It got stuck half way, and after half an hour I was able to remove the solid object, cook it and serve it to my little sister.
So here I repeat:
People, I've tried it and its not possible to shove a potato(a big one) up my ass. Stop asking
This is also a request from pie in another thread.
