Its the one with W sitting at his school desk, looking like the slacker/class clown he is, saying to Congress (portrayed as Uncle Sam) "Yo teach - how 'bout another extension" while holding his Iraq report with a bunch of failed test papers from prior years laying on the floor and a calandar labeled September hanging on the wall behind him.
Unfortunately, in the one that will appear in tomorrow's paper, W gets the last laugh - see the Sept 11 cartoon with General Petraeus using the same link posted above.
