Did you know that Paul Henning originally planned on having the Clampetts move to New York. Because filming in NYC, was too expensive, the series setting was moved to California. The season 8 episode where Jed builds a log cabin in Central Park deals with conman Shifty Shafer [Phil Silvers] selling the Clampetts the entire park. As for the Andy Griffith show "struggling" after Don Knotts left after season five, I would tend to disagree. In Don's last season, the series ranked 4th in the Neilsen ratings. The final three season ratings were 6th, 3rd and 1st. I don't call that jumping the shark. The only reason the series ended was because Griffith had tired of the roll. It remains one of only three series in North American television history to be #1 in the Neilsen ratings at a series ending. I Love Lucy and Seinfeld are the other two.

The Simpsons, when they revealed that Principal Seymour Skinner was an impostor. And then at the end of the episode everyone was ordered never to talk about it again.

Not to mention the terrible way they dealt with the Apu controversy.

as happens often with these types of lists the way the article characterizes the the Beverley Hillbillies move to NY and Central Park is wrong. There were only two episodes in 1969 when they were in NY. Phil Silvers as Shifty Shavers was on those as well as 4 subsequent episodes including one in Washington where he sells the Clampetts the White House.
