Appearing in a pretaped spot during Comedy Central's "The Colbert Report" on Thursday, Bush hailed the military.
"Your achievements in Iraq have earned you a special place in American history. You are men and women of great courage and endurance - and that's gonna come in handy," Bush noted, winding up to zing Stephen Colbert, the blustery "Colbert Report" host: "I've sat through Stephen's stuff before."
Bush said former first lady Laura Bush joined him in the shout-out.
"The Colbert Report," with Colbert as its comically pompous, conservative host, originated this week from Camp Victory on the western edge of Baghdad. The show's home base is Manhattan.
