The 50-year-old Australian actor revealed Michael would relentlessly joke call him in hotel rooms, reported The Guardian.
"For two or three fucking years. I never met him, never 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.
"'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?," he said.
