Rock et Belles Oreilles, often referred to as R.B.O., was a Québécois radio, television and stage comedy group that was very popular in the essentially French-speaking Canadian province of Quebec during the 1980s and 1990s. Its name was a pun on the name of the famous Hanna-Barbera blue dog character Huckleberry Hound ("Roquet Belles Oreilles" in French). Rock et Belles Oreilles came back for a New Year's Eve special on December 31, 2006, "Le Bye Bye de RBO" and did it again in 2007.
