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.
Scrappy Blumer
Blumer learned to fly whilst in Washington, and on March 23, 1942, enlisted in the Army Air Corps. After basic training, he was sent to the flight school at Luke Field, Arizona. Blumer received his wings on March 10, 1943, and was then posted to Marysville Cantonment, California, to join the 367th Fighter Group. It was at Marysville that Blumer earned the nickname "Scrappy", after holding his own against two Marines in a drunken brawl.
