This forum thread from our friends at Giant Bomb is freakin' hilarious (some images NSFW). Its title is "Add an inconspicuous MS Paint c*ck to a well loved Genesis cover," and I love forum user BiffMcBlumpkin for making it.
It's exactly as it sounds: Take a Sega Genesis game cover and add some junk, via MS Paint, to a character on the cover. No one escapes. It starts with Phantasy Star IV (an easy one), and continues with Shinobi, Taz Mania, and even the beloved Streets of Rage 2. The Vectorman one (pictured above) almost made me cry with laughter.
I can't tell you how hard I laughed at these. It may be juvenile, but it's so funny that we don't care. I'm waiting for that guy who hates game journalists to tell me how this isn't news.
As Giant Bomb is our official/unofficial Game Site that We're Totally Cool With, maybe Destructoid readers can contribute to this forum thread. I know you all have it in you.
