Happy birthday, Michael Jackson! You've hit the big 5-0... and you don't look a day over 12!

Despite all the rumors about his bizarre personal life, the man is the undisputed King of Pop... and for very good reason. Let's take a look at the musical genius at work in perhaps his finest hour:

Michael Jackson & Eddie Murphy: "Whatzupwitu"

Oh god. No, that didn't work. Now I just feel dirty. Is there some way to cleanse the pain?

Michael Jackson & Roberta Flack: "When We Grow Up"

Okay. I feel slightly better.
