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.
Creepy Crespi
Frank Crespi's nickname, 'Creepy', is widely considered one of the more colorful and unusual names in baseball history. In a 1977 radio interview with future hall-of-fame broadcaster Jack Buck, Creepy was asked if people still called him by his nickname (answer was yes). Jack followed up with, "Why do they call you that?" Crespi replied, "Well, it's an involved thing...I used to hear a lot of different stories. But I think the best one is (from) some sportswriter. He said the way I creep up on a ball, because I run low to the ground after a ground ball."
