In May 1978, long time World Wide Wrestling Federation (WWWF) manager "Captain" Lou Albano introduced a new team, the Yukon Lumberjacks, composed of Lumberjack Eric and Lumberjack Pierre. The ring characters of Eric and Pierre were that of Canadian lumberjacks, complete with flannel shirts, bushy beards and wild hair. The Lumberjacks worked their way up the tag team ranks quickly starting a storyline with the reigning WWWF Tag Team Champions Dino Bravo and Dominic DeNucci, including several inconclusive championship matches. On June 26, 1978, the Yukon Lumberjacks defeated Bravo and DeNucci to win the championship. As a team they successfully defended the championship against teams such as Bravo and DeNucci, Gorilla Monsoon and S.D. Jones, Haystacks Calhoun and Tony Garea, and Chief Jay Strongbow and Larry Zbyszko, as their reign lasted 148 days. The Lumberjacks lost the championships to Tony Garea and Larry Zbyszko on November 21, 1978.
After losing a rematch the following day, Eric left the WWWF, ending the Yukon Lumberjacks. Lumberjack Pierre remained in the WWWF until early 1979, when he also left.
