"Furt" is the eighth episode of the second season of the American musical television series Glee, and the thirtieth episode overall. It was written by series creator Ryan Murphy, directed by Carol Banker, and premiered on Fox in the United States on November 23, 2010. The episode features a guest appearance by actress Carol Burnett as a Nazi hunter and mother of cheerleading coach Sue Sylvester (Jane Lynch), who shows up for the first time in years, just in time to attend Sue's wedding to herself. The long-anticipated wedding of Burt Hummel (Mike O'Malley) and Carole Hudson (Romy Rosemont) is also featured, and the bullying storyline reaches a climax that results in Kurt (Chris Colfer) transferring from McKinley High to Dalton Academy at the end of the episode. The episode features covers of four songs; they received generally favorable reviews. Three were featured during the Hummel–Hudson wedding sequence, and the two songs by Bruno Mars, "Marry You" and "Just the Way You Are", charted both on the Billboard Hot 100 and internationally. Burnett's appearance, and her song with Lynch, were lauded by most critics, as was the central wedding of Hudson and Hummel, but Sue's wedding to herself was widely panned. Additionally, a few reviewers, including The Atlantic Kevin Fallon, thought the bullying storyline had been stretched over too many episodes. Upon its initial airing, this episode was viewed by 10.41 million American viewers and garnered a 4.0/12 Nielsen rating/share in the 18–49 demographic, its lowest for the second season to that point, and down substantially from the previous episode, "The Substitute".

Principal Sue Sylvester announces her intention to marry herself, and glee club member Sam Evans offers fellow member Quinn Fabray a promise ring.
