1. You find yourself working the word 'Jujumagumbo' into conversation.
2. When your with your friends you start doing the fist bump.
3. USA Networks bans you from sending them a new script for Psych episode every week
4. You actually think Shawn & Gus are real people.
5. You find yourself arguing with your friends about how Psych is the best show on television.
6. You try to divine the amount of hats in any given room. (beanies don't count).
