Casting Bentley Gregg's houseboy was difficult as well. Sammee Tong was cast based primarily on his experience as a stand-up comedian. Forsythe believed much of the program's success resulted from the interaction between Tong and himself and that Tong had great comic timing. He also stated that Tong's character was unique for the time and that he was not the "typical" Asian house servant. Forsythe insisted on Tong being a major character on the program. Several of the program plots center around Tong, many dealing with his attempts to improve his position in life. Although none ever pan out (much like Bentley or Kelly) he does develop as a character through the life of the program.
