In light of recent news about Mr. Roy Horn, I am presenting you with a few easy steps to avoid an attack by Oscar the Grouch. (cue Fox's stereotypical 'When Animals Attack' music)
Now as unlikely as this might seem, grouches are very dangerous animals. As you might know, grouches natural habitat are in the wild, among other grouches.
These grouches include, but are not limited to: Michael Moore, Bill O'Reilly, Me!, Archie Bunker, and many others!

Please take heed of my warning, and I hope you find this tutorial helpful.
And by the way, "You're Welcome!!!"
