Help!

For the yearbook's senior superlative's I was nominated as 'Most likely to be seen at ComiCon'. On wednesday we take our pictures for our yearbook (we don't find out if we won until the yearbook is released OH JOY) IDK what props to bring or how to pose tho. I'm thinking of wearing my gryffindor scar, and maybe bringing a comic book and my ps3 controller BUT IDK. I know one of the other girls that also got nominated it bringing a lightsaber and Darth Vader's helmet WTF how do I compete with that? lol

TL;DR please give me suggestions on how to pose/what to bring!!!!
