Russell Crowe has revealed Michael Jackson repeatedly prank called him with bad jokes for years — even though the pair had never formally met.

The Aussie actor claims MJ started prank calling him after he found out the fake name Russell used to check into hotels.

“For two or three f---ing years, I never met him, shook his hand, but he found out the name I stayed in hotels under, so it didn’t matter where I was, he’d ring up do this kind of thing, like you did when you were 10, you know,” he told The Guardian.

“[He’d say], ‘Is Mr Wall there? Is Mrs Wall there? Are there any Walls there? Then what’s holding the roof up? Ha ha.’

“You’re supposed to grow out of doing that, right?”

And it sounds like he’s holding onto it. Rusty told a similar story during a 2013 interview with The Sun.

“He’d ring me and in a strong voice and say, ‘There is an emergency and you need to leave the building,’” he revealed.

“I’d ask, ‘Who is this?’ And he’d say, ‘Do not worry Russell, just kidding, this is Michael.’”
