The sobbing cart was inspired by one of the comics here.
In other thoughts, this comic is a tribute to the kafras, who never hold up their noses in disgust at all the sick things we make them carry! Hearts, human cerebrum, 5-month old milk, poopoo hats, sticky mucus (what is that stuff, really o.O), chunks of iron & steel, skulls, legs, tongues, stones, various other monster body parts, billions of Jellopy... you get the idea. The list goes on forever!
