How did Michael Jackson challenge the victim's parents? "Then why won't you slap my face, because I'm bad?"
Michael Jackson's Challenge
Explanation
Explain Bear
Listen up, buttercup. This joke is for dum-dums, like you. It's a play on Michael Jackson's song "Bad". Instead of asking why someone won't attack him, he's asking why the victim's parents won't slap him, because he's "bad" (meaning naughty).
