Sure, there's going to be lots of jokes about Michael Jackson. More than ever before. Very few of them will be funny, even fewer will be original.
I'd like to step forward and encourage people to try harder than they otherwise would and make jokes that reference more obscures songs from either the Michael Jackson catalog. Can the "Beat It" reference, go instead for "Prison? I bet he's never Ben there before." Leave off anything about the kid not being his son. Instead, explore "I think these accusations are completely Off the Wall."
Yes, the lines I favor are more work. And perhaps not even as funny. But they're better for your brain and better for the world.
I'm going to keep thinking of more and I encourage you to do the same. Feel free to send me your ideas.
