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.
List of M*A*S*H characters
Sparky (Sgt. Pryor) is the mostly unseen telephone/radio operator at headquarters. His nickname is probably a carry-over from the days of telegraphy. ("Sparks" is a similar nickname, as used, for instance, by Ellie's father in the film "Contact".) Radar almost always needs to go through Sparky when he makes a call to Seoul, Japan, or the U.S. (Sparky seems to be at his desk round the clock.) Sometimes, for special calls, Sparky requires a bribe to arrange the connection. The character is seen and heard only once, in the first-season episode "Tuttle". This is also the only time his rank and real name are mentioned. He is portrayed by Dennis Fimple, who plays him with a noticeable U.S.-Southern accent.
