Charley - Magoo's Chinese houseboy - Charley was controversial as he was depicted as a Chinese sterotype and using "Asian" type renderings of English such as referring to himself in the third person as "Cholley" and calling Mr. Magoo "Bloss" instead of Boss. Around the late 1960s episodes with Charley were dropped from the series and his character was never mentioned again.
