My brothers kid is going through a rebellious phase about cleaning his bedroom and I decided to help:

My Nephew: I feel like Dad's always making up rules and stuff.
Me: Like What?
My Nephew: Like if I don't clean my room a portal will open and take me to another dimension.
Me: Well that's what happened to your older brother.
My Nephew: What older Brother?
Me: Exactly.
It's been a week since then, and his kept that room sparkling clean...
