I don't know who this twisted genius is, but this could be the best scare prank I've ever seen!

A lunatic dog owner decided to dress his cute dog in an amazing spider costume, and put him in situations to SCARE THE LIVING CRAP out of unsuspecting people in the dark!

Freaking GENIUS!

The elevator bit is awesome, as is the subway entrance, where the dog overtakes and outsmarts the guy he's chasing!

Be warned, if just the idea of spiders creeps you out too much, this might send you into a coma.  For the rest of us, it's funny and cute as hell to watch this puppy running around happily dressed as a huge spider!
