The FAA Can't Stop People From Throwing Live Turkeys Out Of Planes
UPDATE: Some interesting comments:
The story (although it may be apocryphal) is that the origin of the WKRP episode traces its roots back to my home town of Phillipsburg, KS where they threw turkeys off of the top of the courthouse believing they could fly. As the story goes, a young Gordon Jump (who would later play Mr. Carlson) covered the event as a radio reporter.
There was once a guy name Ted Stepien from Cleveland who was a complete and utter moron, but he was rich (sound familiar?). He was universally acknowledged to be one of the worst team owners in any sport in US History. The NBA actually passed a rule to prevent teams from making the stupid trades that Stepien made.
Anyway, Ted also owned a local softball team, and decided to celebrate the 50th anniversary of Cleveland's tallest building by tossing softballs from the top. Here is a link to what happened next.
I went to college with a girl whose dad played on that softball team, which is how I know the story. For the longest time I thought this was the genesis of the WKRP episode, until I realized this happened TWO YEARS AFTER the show.
Stepian was copying a stunt from 40 years earlier.
