Hey, Sean Penn's makeup artists have to terrorize someone do something in their off time.
Actually, we're not sure who gets the credit for Mel Gibson's sad clown face (we're guessing no one's going to be tripping over themselves for the association), but just in case you were wondering what the embattled actor went as for Halloween this year, here's your answer. (Condolences to everyone who had money on "employable actor.")
And if you were wondering what crazy brave soul decided to extend the invite to Gibson, we'll have you know this stunning photo was taken outside of David Arquette's spooky shindig. Guess actors who don't know when to shut their traps gotta stick together.
Sad Keanu, you've got some competition.
