After swirling rumors that Kristen Wiig and Andy Samberg--along with costar Jason Sudeikis--would be leaving the cast of Saturday Night Live at the end of the 2011-12 season, Ms. Wiig and Mr. Samberg were indulged with tributes during this weekend's season finale. At episode's end, Ms. Wiig was serenaded by the Arcade Fire in a graduation-themed set piece during which she danced with the cast, individually, then producer Lorne Michaels. Former cast members like Amy Poehler and Rachel Dratch joined in as well.

Andy Samberg made his own farewell tribute, performing in "Lazy Sunday 2," a sequel to his breakthrough "digital short" in 2005 and a manner of closing up loose ends.

The Saturday Night Live farewell, while not de rigeur (if Mr. Sudeikis is in fact leaving, he may feel a bit left out this morning), occurs from time to time; Amy Poehler's less elaborate farewell in 2008--interrupted by Fred Armisen's David Paterson stumbling through the shot--was heretofore the most memorable.
