“I’m a giant carp, Andy!”
“I know you are, Herb.”
Funny thing about that episode (called “Fish Story”). It was written by series creator Hugh Wilson, though it’s credited to the pseudonym Raoul Plager. Wilson was getting demands from the network to add more physical comedy and general “wackiness” to the show. He wrote “Fish Story” to be deliberately as ridiculous, over-the-top, and dumbed-down as possible, in the belief that it would demonstrate how those sort of hijinks just didn’t work for WKRP. He was confident that the audience would utterly reject that kind of “cheap, low-brow” comedy.
To his horror, the episode was a huge hit, and has become a fan favorite. To this day, he continues to hate it.
