Despite being one the most talented men to ever walk the planet, Michael Jackson's lifelong ambition to resemble Peter Pan has had a devastating effect on his career. Tales of how he sleeps in hyberbaric oxygen chambers and how he purchased the bones of the real-life Elephant Man left fans scratching their heads, and the term 'Wacko Jacko' was born. Christ! Get me some "Jesus juice" to calm my nerves.
