In January 1983, Sharpe entered the World Wrestling Federation, where he would stay until his retirement in 1995. He was a regular of WWF programming throughout the mid-1980's and early 1990's. He was announced and self-proclaimed as "Canada's greatest athlete". Initially in his WWF career, he was managed by Captain Lou Albano and received a sizeable push, regularly defeating jobbers after smashing them with his forearm. This culminated on April 30, 1983, with a match against World Heavyweight Champion Bob Backlund, where Sharpe was defeated and would never reach such main event heights again. In fact, Sharpe was primarily used as a jobber to rising WWF stars in television tapings.
While Sharpe's television appearances were always as the role of a jobber, and victories even at house shows were rare, he chalked up quite a few untelevised victories between 1984 and 1988. Sharpe had a few more memorable moments over his WWF career. He appeared on Piper's Pit in 1984, provided the opposition in Ivan Putski's 1987 comeback match at Madison Square Garden, and pinned Boris Zhukov to reach the second round of the 1988 King of the Ring tournament.
On January 17, 2016, Sharpe passed away.
