THUMBNAIL REFERENCE:
I can't believe it has taken me this long to play off the R-rated cult classic, "American Psycho". I whipped up my take on the movie poster in Photoshop. I am sorry if you thought there'd be more American Psycho references in this video. I toyed with the idea, but it was cutting against the spirit of the content.
