Have you ever seen Eminem smile? Never, right? It's one of the rarest things in the world and I honestly could only find just one really old picture of him with an almost smile on his face. 

So, if you've ever wondered what he would actually look like with a full-blown, toothy smile, someone is here to make all your dreams come true. Mike Brown has a superpower - he can make every celebrity smile and the result is high-key terrifying.

There's so many more.

It's not over.

He's made Grammys winners sad as well.

And made Ellen sad.

This is the worst one.
