1. Wtf? One day this guy's playing dress up and the next he's wearing a fucking flood napkin.

2. The city of New Orleans should have listened to its mother and put on its flood napkin before Hurricane Katrina. Maybe if it did it wouldn't have caught millions of dollars worth of property damage and a bad case of poor black people stealing stuff.
