Baseball Card Vandals is a Tumblr pretty much dedicated to the art of drawing dicks on cardboard. And it should be considered an art, right? A well placed Sharpie wang and balls can bring hours of enjoyment!
With a gallery of "decent jokes on worthless cards", this is the kind of website that you can waste a lot of time on... and I mean that, I started this article two hours ago. Enjoy!
