Is This Hilarious Or One Of The Meanest Pranks Ever?

This is what Halloween is all about.  Trick or treat!  With that being said, give me the treat because if someone tried to pull this prank on me, I'm not sure if I'd pee or poop myself or just kill the person who pulled the prank.  What about you?

This might be the meanest prank I've ever witnessed. Brazil has a TV channel with a tradition awesome practical jokes and hidden cameras.

The latest prank includes the doll from the movie Annabelle coming to life and locking the unsuspecting cleaning people in the room with her as strange stuff begins to happen.

The video is in Portuguese, but don't worry, fear has no language barrier.
