I was sent home early on my first day of kindergarten because I refused to stop singing "Beat It." Seriously. Other MJ memories: being too scared to watch "Thriller" with the rest of my band class in middle school, and thinking "Captain Eo" was phenomenally cool when I visited Disney World. I even had a Captain Eo watch. May he rest in peace. (Hat tip to Greg for pointing out the video that follows.)
Five favorite Michael Jackson songs, off the top of my head, in no particular order:
"Black or White"
"Man in the Mirror"
