THEY are one of the most beloved comedy duos of all time, with their characters Wayne and Garth set in stone as 90s icons.

But behind the scenes, comedians Mike Myers and Dana Carvey have had a rocky relationship.

Talk of a feud between the pair, who started playing rock-loving slackers Wayne and Garth on Saturday Night Live before transferring to two hugely successful Wayne’s World films, has been bubbling for years.

In a new interview with Howard Stern, Carvey, 61, admitted he and Myers had never even planned on becoming a duo, so found the relationship difficult at times.

“We were never meant to be a comedy team, Mike just invited me into the [Wayne’s World] sketch. I’m grateful that he did,” he said.

With his odd affectations and bizarre non-sequiters, Carvey’s Garth was the perfect scene-stealing sidekick to the more straightforward Wayne. When the pair’s SNL sketches became cult hits, Myers started working on a big screen outing for them — but it was rumoured he tried to prevent Carvey from appearing in the film for fear he might be upstaged.

The real kicker for Carvey, though, came years later, with the release of Myers’ hugely popular Austin Powers films. Powers’ arch-nemesis was Dr. Evil, instantly recognisable with his cocked pinky and arch manner.

While he was a broad parody of James Bond villains, Myers’ Dr. Evil was also remarkably similar to impressions Carvey used to do of SNL producer Lorne Michaels on set.

“ ... With the pinky coming out, yeah. When I first got on SNL, no-one was doing [Lorne]. It’s a really funny affectation, because it’s so specific,” Carvey said, admitting that it took him a long time to get over the alleged character theft.

“Umm ... I’m in therapy now,” he told Stern. “When you look back at it, you get a better perspective.”

The pair did finally bury the hatchet, appearing together at a Wayne’s World reunion panel in 2013 — some 21 years after the original film’s release.
