What to wear: Dustin's red, white, and blue baseball hat shouldn't be hard to mimic if you buy a plain white hat and some red and blue paint. Once that's done, pick up a curly brown wig, an old-school graphic t-shirt, some brown cords, a denim jacket, and a backpack. Also consider getting something to make it look like you're missing your front teeth.
How to act: Dustin is a total scene-stealer, so you should be, too. Get ready to bust out some tricks this Halloween (like cracking your arms in a cringe-inducing way, for instance), and make sure you keep your friends laughing.
