I decided to help you out again this year, slacker.
PSY, Gangnam Style Music Video
Duh. I have a feeling PSY look-alikes are going to be riding their imaginary steeds all over the country this year. So you're not going to stand out in your blue tuxedo jacket and bowtie and shades, but you at least know in ten years you can look back on the pictures you took this holiday and wonder what the fuck you were supposed to be. For the pros: Get one of your friends to dress as the guy in the yellow suit, and your other friend to dress as humpy-humpy guy in the elevator. You could also ask someone to precede you with a giant fan and spray trash in your face all night.
Maddie The Coonhound, Maddie on Things
To truly capture the essence of Maddie the Coonhound, you're going to have to focus more on your energy and state of mind than your physical props. You can make a quick dog costume by cutting out some floppy dog ears (you can use felt or brown paper or even a paper bag!) and tape them to a headband, and paint a dog nose on your human nose, and make a tail and wear a collar. Then all night, be very patient, and polite, and climb up to very high, precarious, unexpected places and just stay there. For the pros: This would work really well if you have lots of sunspots on your skin. Brandon, Shame
Dress really sharply, comb your hair neatly, speak with just the barest hint of an Irish accent. Also get a huge fake dong and hang it out of your open fly. The girls will love it. For the pros: FUCK EVERYTHING.
Hannah Horvath, Girls
Strip on down to your birthday suit and be kind of awful to everyone. Don't forget your cupcake! For the pros: Do not, I repeat, DO NOT go to the bathroom alone or let your bffs go to the bathroom alone! This includes doing number ones and number twos and also bathing. Don't forget your cupcake!
The Higgs Boson, The Beginning of Space and Time
Pipecleaners. For the pros: More pipecleaners.
