I was watching Futurama the other day (The Day the Earth Stood Stupid) and what did I hear? Rather than joining the Reform party like every other time I watched that episode, suddenly they're rushing out to join the TEA Party. I had to rewatch that segment a couple times because I couldn't believe that I was hearing things correctly.

So, what's up with that sort of thing, and whom do we bloody for screwing with a previously aired show?

I knew I recently read something like this.
Cracked.com article Read #3. It does give a bit more insight.

Ah, thanks. I know that some shows have been edited to remove the WTC from them, and I don't think they've shown the episode of the Simpsons in NYC in over a decade.
