Perry Mason crossover
Keye Luke and Philip Ahn were in the Perry Mason episode "Case of the Weary Watchdog," the title referring to a Chinese statue. Luke is spouting truisms exactly like his character in "Kung Fu." Makes me wonder if he ever adlibbed in "Kung Fu."
There's a Philip Marlowe radio mystery called "Case of the Orange Dog" also about a Chinese dog statue- for some reason they made good macguffins back then.
