I knew this was the 'jump the shark' episode when i saw Andy and Howard playing CHESS?! Checkers was always the boardgame in Mayberry. Andy looked so serious staring at the board in one shot. Of course the board was set-up wrong: the lower Right square is always a white one on a chessboard that's been set-up properly. I love all the TAGS episodes but this episode spelled out the end for me personally.
