Charlie O. the mule.
Charlie-O the Mule was the mascot used by the Kansas City Athletics and Oakland A’s from 1963 to 1976. The mule was named after Charles O. Finley, the team’s flamboyant owner at the time.When the A’s moved to then heavily Democratic Missouri, where the official state animal is the mule, Governor Warren Hearnes gave a mule to Finley for his barnyard menagerie at Municipal Stadium which also included sheep and goats that scampered up the hill behind right field. The Municipal Stadium menagerie also included Warpaint, the horse mascot of the Kansas City Chiefs. As questions swirled about whether Finley would be loyal to Missouri, he embraced the mule and removed the elephant from the A’s logo and changed the A’s colors from blue, red and white to green, gold, and white.When the Athletics left Kansas City after the 1967 season, there was debate about whether Charlie O should stay behind in Missouri, but Finley decided that the mule had been a gift and took him with him to Oakland in 1968. The mule died in 1976 at age 20. He was cremated, and the location of the remains is secret. (Wikipedia)
