You've probably been seeing a ton of last minute geeky costume ideas all over the internet (my particular favorite post is over on Io9)
But I recently heard of a costume idea that might possibly be the best idea ever.
It's Arthur from Inception. And here's how you do it.
-One striped, long sleeved button up
-Brown suit pants
-Brown hair, slicked back
-A backpack (right?)
-A few blow up dolls
I think you see why this is awesome of the awesome. Due to how expensive and time consuming blow up dolls and helium are, I will not be seeing this costume in the flesh this weekend, but if YOU pull it off, please take some photos and send them to me! I promise you'll win at least one costume contest this weekend if you can rock this shit.
You can credit this idea to @csharp7.
