Halloween, what a fucking weird ass holiday. Why not make it a full-on day to un-teach our children everything we've taught them.
The day would go something like this:
Wake up, have a big bowl of candy for breakfast, don't brush, wash it down with a Coke. Have a quick demonstration on how to make and shoot proper spit balls. Make it clear they are not allowed to flush a toilet or put a seat down all day.
