Jon Stewart pulled out his circa-Bush era "Mess 'O Potamia" graphic to catch his audience up on what's happened in Iraq.
Videos of militants running rampant in Mosul, Tikrit and Baghdad caused Stewart to say, "What the f*** is going on over there?!"
"Who are these militant over-achievers?" Stewart asked about the groups taking over Iraq. He riffed on the militant leader Baghdadi, who has a PhD in Islamic studies: "Did you hear that ladies? He's a doctor ... a brutal doctor. I guess we should have been tipped off by his PhD dissertation."
Stewart continued explaining the "Mess O' Potamia" and concluded his skit with the news that since the Iraqi government is now asking the U.S. for help, "Yes we did it! We finally got it so that Iraq will now greet us as liberators! Way to go, everybody!"
