On May 17, 2006, Colbert introduced "Better Know a President", a 43-part series that would refresh the viewer's memory of the accomplishments of every President in United States history. The first president covered was Theodore Roosevelt, played by Roosevelt impersonator Jim Foote. In keeping with the running gags of the segment, he asked Roosevelt if the Spanish–American War was merely a great war of American imperialism, or the "greatest" war of American imperialism. The second covered was Thomas Jefferson. Colbert talked to three different Jefferson impersonators, and judged which was the best.
