If you haven't gotten a happy meal recently, the ones that come in the traditional cardboard boxes (not the sacks) have the creepiest face imaginable on there reminiscent of Annoying Orange. Why not use this as a cheap costume idea?

The instructions couldn't be easier, I don't think. Open the box from the bottom and stick your head through the box.

Done!

Yeah, I suppose you'll have to cut something out so you can actually see through it, and I had to cut it form the back as my Frankenstein-sized head wouldn't fit through it, it made for a fun picture.
