Apparently Michael Jackson was a real practical joker.

In an interview with The Guardian, Russell Crowe claims that Jackson consistently prank-called him "for two or three f---ing years," after Jackson discovered the fake name Crowe used to check into hotels.

The anecdote raises two very important questions that, sadly, remain unanswered in the article: 1. What name does Russell Crowe use to check into hotels? and 2. How did Jackson discover it?!

But here's what Crowe does reveal about his strange relationship with the late singer - whom he never actually met in person: "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?"

Crowe previously brought up the bizarre prank calls in a 2013 interview with The Sun.

Michael Jackson. What a character.
