Cereal (Serial) Killer Costume

I made a last minute decision to dress up for Halloween, but with slim picks in the stores and to revealing to trick-or-treat with my daughter and her friends I opted make something that was quick and cheap. I basically bought the variety pack single serve cereal at the supermarket for $5.00 and a can of blood from our local party store. I removed the cereals from the packages and cut the covers and pinned it all over my shirt and sprayed my self with the can of fake blood (dabbing some on my face), and used a prop knife from a previous costume. Whalah!! Cereal Killer.
