From the story in the bible, Boris:3:14, it mentions the baby Jesus (they were still callin' him baby Jesus even though he was now 7 years old) went out for his first Halloween dressed as The Frankincense Monster and he sadly came home with a bag filled only with myrrh.
The next year he would dress up as Cowboy and get a bag of gold.
The point of the story?
Ya dress up like Frankincense, ya get myrrh. Dress up like a Cowboy, and ya get gold.
It's true. I read it in the bible. Elvira 36D:
