9. The Chickeneers perform 'Ho Hey'
March 28, 2013
Jimmy Fallon, Blake Shelton, Nick Offerman, and one of the "Late Night" writers, Chris Tartaro, performed the Lumineers' radio hit "Ho Hey" on March 28 -- but not the conventional way. The quartet dressed as chickens, sang the song in clucks, and assumed the group named, "The Chickeneers." Genius.
