As a child I was absolutely certain that my anus could not possibly open wide enough to let out even a typical sized turd, not to even mention an especially large one. So I was sure that when one pooped, turds somehow magically materialized outside one's anus, giving only the illusion that they actually came out through it. Funny how i never thought to wish that they would materialize just a tad farther out from my anus, so I'd never have to wipe my butt!
