The Onion's never as funny as when it satirizes effete liberal stereotypes that they think right-wing rednecks harbor about effete liberals. Thus, this video about country singers rooting for al Qaeda victory in New York. Missed satire opportunity: None of the country singers are named "Dinesh D'Souza." (This comes via HotAir, who remind us that Michael Moore actually published a 9/12/01 essay asking the terrorists why they attacked a city that didn't vote for Bush.)
Funny (especially the more specific "psst, put the poison here" bit of the song), but not as perceptive as this immortal Mr. Show sketch.
There's American history between October 2001 and March 2003, in convenient "humor" form.
