In 2008, Harrington made his first appearance on the NBC show "Poker After Dark" in the episode titled "Mayfair Club." This tournament brought together poker players who had played at the legendary Mayfair Club in New York City. The other players in the tournament with Harrington included professional poker players Lederer, Mickey Appleman, Steve Zolotow, Jay Heimowitz, and Mike Shictman, the owner of the Mayfair Club for many years. Harrington busted out first, finishing in sixth place. The tournament was won by Heimowitz, who defeated Lederer in heads-up play.
