On Friday, the darkly comedic card game Cards Against Humanity posted an update to its social media and e-mail list followers, which fans assumed might tie into the company's usual holiday-related online promotions. Instead of unveiling a limited-edition holiday-themed set of cards, however, the game maker shut down its online store—with one very, very odd exception.

"To help you experience the ultimate savings on Cards Against Humanity this Black Friday, we’ve removed the game from our store, making it impossible to purchase," the card maker's update read. After that, the company linked to its online store, where, for one day only, it's selling one thing: bullshit. Literally.

Though the page link only showed a typical Cards Against Humanity-styled box, complete with Helvetica Bold font and a cartoon version of a poo drawn on the side, the purchase page assured shoppers that the box contained "literal feces, from an actual bull." The site advised shoppers who spend $6 on this curio to "fertilize your garden, adorn a festive tree, or surprise a loved one with the gift of poop." The company spent most of Friday morning assuring its Twitter followers, again and again, that yes, this box will contain nothing more than poop. (Company co-founder Max Temkin offered the following to one fan: "If you buy the poop expecting it to be something else that’s not poop, you’re actually buying a valuable life lesson for $6.")

Unlike other card packs for the game, this product does not appear to be an Amazon exclusive, and we trust that the store means it when they say it will only be sold for one day. (Update: The poop sold out within half an hour of this report going live.) It's as irreverent a Black Friday protest as we've seen, though we think protestors at big-box chains like Wal-Mart might have been more effective if they had a few boxes of Cards Against Humanity's bullshit in tow. The company's update reminded fans that they can still buy into its other 2014 holiday promotion, "12 Days of Kwanzaa or Whatever," until Monday, December 1.
