"......Dude." - a reference to a scene in BASEketball when Coop and Remer are arguing, and they start saying "Dude" to each other in various ways. It's an extraordinary thing when you can have a whole conversation with just one word uttered back and forth between two people.
"Aw, aw, awww!" - normally a Trey Parker line, Matt Stone says it here.
Bush sounded like Dr. Evil on Wednesday's ep, but more presidential in later airings.
"He died like a pig" - Line said in The Untouchables (1987) by Frank Nitti (Billy Drago).
Bush's staff looks like the bad guys in the Jean-Claude Van Damme movie Hard Target I'm sure Bush's plan has been mentioned in all sorts of 9/11 sites. Here's the breakdown...
"All I had to do was have explosives planted in the base of the towers. (so the towers can buckle from below instead of from on high)
Then on 9/11 we pretended like four planes were being hijacked when really we just rerouted them to Pennsylvania, (so no actual passenger planes were lost)
then flew two military jets into the World Trade Center filled with more explosives, (the two planes that struck the towers)
then shot down all the witnesses of Flight 93 with an F-15 (instead of the passengers preventing the hijackers from hitting their target, which may have been the White House)
after blowing up the Pentagon with a Cruise missile. (since the hole shown on the Pentagon was too small for a jet plane to make).
Finally we could invade Iraq, and get the oil which made us all richer than before. (which has been touted by skeptics as the one and only reason we went into Iraq)"
"the False Flag policy" - this policy says that some attacks that seem to come from enemy nations are actually self-inflicted and covered up by blaming someone else. In the case of 9/11, the policy is that the US government performed the attacks, but made it look like Saudi Arabia did it (most of the terrorists who supposedly hijacked the planes were Saudis). This video, TerrorStorm, from Alex Jones, explains more about False Flags and other things concerning terrorism. Here's an older Alex Jones video: 9/11 The Road To Tyranny.

The restaurant the boys pass is McDonald's, but the M is inverted to a W. This is also done in anime so the studios don't have to pay McDonald's for using the logo.
If anyone wants to read more about South Park and 9/11, there's a long thread on the South Park Studios BBS about it.
Last but not least, a detailed e-mail from Larry Patriarca about the truth behind 9/11
