Dr. Ken Jeong may play a (neurotic) Chinese American on Community, but his character apparently can write in Korean. Back when Señor Chang made life hell for his Spanish language students, he was seen scribbling across the blackboard. In two quick flashes, Korean was visible. It appears Ken was writing his birth name "Jeong Kang-Joh." No wonder Señor Chang's Spanish students were so confused!
