Great Idea for a Sketch

With that new Fox News comedy show being developed, I'm sure there are some great comedic minds working to make it the best Daily Show rip-off ever. But I've got an idea for a hilarious sketch.

The sketch opens with George Bush making an address to a large crowd. Then he starts looking for WMDs all over the stage -- under the podium, in the wings, in the first row of the audience. Hilarious! He just keeps looking and looking and can't find 'em!

And then he finds 'em under a pile of 3,000 dead US servicemen.

I think it would be awesome but I have a feeling that it's already been done. I seem to remember this being pitched to someone else, like the American people or something.
