A Michael Bublé Christmas is a television special which aired on NBC on December 6, 2011. Oscar the Grouch was a special guest with Michael Bublé for the special, which also featured Justin Bieber, Tracy Morgan, Kellie Pickler, and Ed Helms.
In the special, Michael finds Oscar's can on stage, with a sign reading "Don't Open Until After Xmas." The lid is opened and Oscar thinks he's avoided Christmas, but Michael points out he hasn't. He then sings to him "Have Yourself a Merry Little Christmas", while Oscar makes comments during the song. Afterward, he goes back into his can, but softly wishes him a merry Christmas.
