To be clear, WKRP was not about successful people winners who run into funny situations. Like Seinfeld or Cheers or MASH. WKRP is really about assholes who can't help themselves who are way in over their head and probably should be driving cabs or waiting tables or working at grocery stores. If anyone would hire them, except for Andy, Jennifer, Johnny, Venus who could probably be successful working at major radio stations in big markets.
But with WKRP, it's these assholes who think way more of themselves that they could ever be in their best drunken or marijuana fantasies, who happen to be working at a radio station in a major city, but small market in Cincinnati who regularly find themselves in these impossible, hysterical situations because they can't help themselves. They don't know what the hell they are doing, they are in way over their heads and have way too much responsibility. And as a result are always screwing up and the turkey drop episode is the perfect example of that.
The whole line with Arthur Carlson the General Manager at WKRP played by Gordon Jump saying that "God as my witness, I thought turkey's could fly is the perfect example of what this show was about. Carlson gets this brain-dead idea that as a promotion for his station he's going to give out free turkey's for Thanksgiving by dropping them in the street from a helicopter. "What could possibly go wrong with that?" Is what you would be thinking when you don't know any better.
