I hope all pictures of my fourth grade Romana I Halloween costume (complete with homemade Tracer!) have been lost.

Because Io9 is collecting pictures of Best (or Most Humiliating) Halloween costumes.

It never occurred to poor little deluded fourth-grade me that not a single person would know who I was... 

 

...and that when I explained, I would experience either heavy mocking or the dreaded "...oh" response.  Growing up geeky.  Sigh.
