In Michael Jackson's weird and "whacky" world, I guess it should come as no surprise to learn that he referred to Macaulay Culkin as "Doo Doo Head".
According to papers released by Californian judges, in addition to using that rather odd nickname, Jackson also set up a secret Neverland society.
The papers also contain a photograph of Culkin obtained from Jackson's bedroom, with the following written on it by Culkin:
"To Apple Head Always remember keep Apple Head Club Doo Doo Head Alive."
Seemingly the Apple Head Club was a secret society that Jackson encouraged his young friends to join.
Sounds normal, right?
