I really should have made The Virgin Spring a triangle, as it is the lone Swedish film up there, but I want to play Left 4 Dead now, so screw it.
I'm addicted to using parentheses, (Ooooh, that's the stuff) I watch a lot of very strange and/or obscure movies, I love videogames, I make promotional videos for sporting goods, I have a totally sweet dog who is lazier than I am, and I will most likely never finish the Sci-Fi novel I'm writing.
