Jim Cramer

Freem replaces superstantial in the opening sequence.

David Kamp

Stephen criticizes Bush for not sending 300 million troops as Stephen advised the day before but he pardons him if this is "the only mistake he makes in this war".

Alex Kuczynski

Wishing viewers a happy Martin Luther King Day, Stephen calls for a nationwide lie-in to refuse engaging in "anything at all", in the style of passive protest such as Rosa Parks, then attacks Senator Barbara Boxer for comments suggesting Condoleezza Rice has no personal ties to the Iraq War.

Still in anticipation of Bill O'Reilly arriving in-studio on Thursday Stephen is more nervous than the day before, bringing out some cherished objects he plans to show O'Reilly the next day.

After the break "Better know a district" continues with Washington's 3rd congressional district representative, Brian Baird.

Bill O'Reilly

The big day is here, so Stephen is crazy with anticipation that Bill O'Reilly will be on the show, stating that his only goal with this show was to see this day, which makes him reveal a "Mission Accomplished" banner and open the last door on his "Bill O'Reilly advent calendar" (in which he finds Geraldo's mustache). He then turns back to US politics talking about Bush's plans to rise the troop levels in Iraq. He then talks about fights between celebrities on his segment "We the MEdiator", rethinking his last week's judgements.

Tom Schaller

Stephen is disappointed at the loss by the New Orleans Saints to the Chicago "God-less killing Machines" Bears. In another "Who's Riding My Coattails Now?", Stephen calls out Bill Clinton for speaking at Knox College after Colbert already had, and artist Terence Koh for selling sperm (in his art) after Stephen's Formula 401 line. The Word is based on the refusal of Alberto Gonzales to admit a right of the people not stated specifically in the Constitution. In another "Stephen Colbert's Balls For Kidz", gambling is discussed.

Jed Babbin

Stephen opens the show by discussing the "problem" with Global Warming and in protest replaces Bobby with a 5000 Watt heat lamp.

The first act opens with a remembrance of Boris Yeltsin. Stephen continues with a combative interview with Eleanor Holmes Norton regarding a recent bill to give the District of Columbia a vote in the U.S. House of Representatives.

David Walker

Colbert decides that a new name is necessary for the long war, and comes up with Freemerican Victernity Made in China. He then backs the idea of having illegal immigrants fight in the armed services in exchange for citizenship. He points out his position on the cover of GQ, then complains about the Four Horsemen of the A-pop-calypse: movies, television, music, and books.

Madeleine Bordallo

Stephen is unhappy at the fact that Stephanie Colburtle The Turtle did not win The Great Turtle Race, after being bested by another turtle named Billy. He claims Billy is a male, and demands a re-race. (After explaining that one can tell the sex of a turtle by the concavity of its plastron, Stephen says that he checks the plastron on "all [his] dates, and if it's not concave, [he is] outta there."
