The Fabulous Kangaroos were a professional wrestling tag team who existed in various forms from 1957 until 1983. The first incarnation of The Fabulous Kangaroos was formed when Italian Australian Al Costello teamed with Australia native Roy Heffernan and adopted an "Ultra Australian" gimmick complete with boomerangs, bush hats, and the song "Waltzing Matilda" as their entrance music. Costello and Heffernan are arguably the most famous version of The Kangaroos, regarded as one of the top tag teams to ever compete in professional wrestling, and are often credited with popularizing tag team wrestling in the late 1950s and 1960s.

Leo Joseph "Joe" Smith Jr. was an American professional wrestler who wrestled as Don Kent and also as The Black Dragon, Doug Kent, Joe Smith and Super Medico III during his 36 years in professional wrestling.
