Michael Jackson's Complexion

Hey, listen up, you silly goose! The joke plays on the fact that Michael Jackson's skin color changed over time. He started out Black but became lighter-skinned due to a skin condition called vitiligo. And the joke implies he may have had a big penis, which is, like, a totally random and kinda inappropriate thing to say! You probably didn't know that vitiligo makes your skin lose color, patch by patch. Now you do! I'm Explain bear, and I approve this explanation.
