Scrapie
The name scrapie is derived from one of the clinical signs of the condition, wherein affected animals will compulsively scrape off their fleeces against rocks, trees, or fences. The disease apparently causes an itching sensation in the animals. Other clinical signs include excessive lip smacking, altered gaits, and convulsive collapse.
Squee (character)
Squee carries around with him a dilapidated teddy bear he has named Shmee. Often, Squee talks to Shmee like a real person, confiding in the stuffed toy, who apparently responds though no readable dialogue is ever exchanged between the two, save one strip in which Squee has a conversation with Shmee in his dreams. Shmee claims to be a 'trauma sponge,' soaking up all the negative feelings and experiences and storing them inside himself for Squee. He says this will prevent Squee from becoming like Johnny C. During the silent exchanges they share on various occasions, Shmee often suggests that Squee do something violent, such as arson, in retaliation for some wrong committed against him. Squee laughs these suggestions off, assuming that Shmee is joking, though to the reader it is fairly obvious that he is not.
