While I know this is a "radio" board, I have to add this bit of info...
A few years ago(O.K. more than a few years ago) someone at Cartoon Network thought running the same cartoon all day on April Fools Day would be a funny thing to do.
The manager at the cable company where I was working started getting calls of complaint from viewers. So many that he wound up getting ahold of somebody at the network and finding out this was a planned stunt.
(I understand someone from "C-N" was looking for work after that event.)
While this was way pre-9/11 and caused no backups on the Interstate nor the closing of a major harbor, it does illustrate the "what were they thinking" observation.
BTW, the umpteen repeated video was a "Screwy Squirrel" cartoon.
