Coolio 

The cheapest Halloween costume ever.

All you have to do is cut off a bunch of tree branches and glue them to your scalp, and you've got the hair down.

Person 1: Why do you have branches on your head?
Person 2: That's supposed to be Coolio's hair.
Person 1: OHHHH. Now I see it. -high five-
