Josh Sundquist is a really impressive guy who makes everyone else's Halloween costumes look stupid every year. I mean, most Halloween costumes look stupid every year anyway, but we pretend that the act of getting several people to all dress up like the Avengers at the same time is one of life's true challenges. Josh Sundquist is there to burst that bubble, because he may have a better perspective on how easy making a Halloween costume is compared to, you know, everything else.
