I do remember Rush (Limbaugh) talking about some inside baseball {Insurance Companies} having to do with the Exxon Valdez oil spill {March 24, 1989.}
He talked about a video, that was made by one of the insurance carries, was showing an animal rights group and a couple of local school classes, releasing some duck's, Sea Otter's, back into the wild.
Out of no where an Orca, shoots out of the water, Sea Otter firmly in mouth, big splash, No Sea Otter.
The purpose of the video was supposed to be look; we @ ABC Insurance company, did the right thing, and here we are 2 year's later, (1991-?) we gave money to the animal Wack-o's, we love children, we love education, etc. You get the drift. They had interviews with the kids, etc.
Well everything went to hell in a handbasket, in under 3 seconds. Orca -1, Sea Otter's ZERO!!!
Moral of the story, throw CHUM into the water, win special prizes.
In my opinion, either they (people of Shark Week) heard Rush (Limbaugh) tell the story, or they seen the video. No way they came up with this idea on their own.
