"While ewoks are often mawkishly portrayed on film as cute, curious little urchins that live in tree houses and coo adorably, the reality of wild ewoks is an entirely different story....The dandy little chaps you’ve seen on the silver screen are just midgets in ewok suits; real ewoks don’t have smooth, clean fur, and no sane human would be inclined to pet one. They’re so plagued by lice, fleas, dander and mange that their coats are spotted with huge bald patches and pocked with weeping sores. Touching one would likely net you a fistful of loose fur, matted with pus and crawling with ticks."
