The Ugly Fish Clock that Klinger displays in his newly decorated quarters shows up in Archie and the Kiss (1973).
Clyde Kusatu who portrays Sgt. Michael Yee has made other appearances in M*A*S*H; playing the officer's club barman Kwang Duk in season 2's 'Officers Only' and 'Henry In Love' and as Capt. Paul Yamato in season 11's 'The Joker Is Wild'.
Sgt. Yee describes the '50 World Series as the Yankees clobbering the Whiz Kids, (The 1950 Phillies nickname because of their youth), 4 games to none. While the Yankees did win 4 games to none, it was hardly a clobbering, the first 3 games were all decided by one run.
