Serious and funny - to me - are not mutually exclusive. The idea of wombats stacking their poop is very funny, but if I was a biologist, that would make me want to investigate the matter even more. During my Zivildienst (https://en.wikipedia.org/wiki/Zivildienst https://en.wikipedia.org/wiki/Zivildienst), I had lots of contact with all kinds of things leaving the human digestive tract. You get used to it surprisingly quickly, as long as you have and endless supply of rubber gloves and disinfectant. OTOH, the revulsion feces inspire in most humans serves a purpose, evolution-wise, so finding a middle ground would be rather difficult.
