Cards Against Humanity is one of the most popular (and offensive) games of all time. Chances are pretty good you've played it at some point.
But DID YOU KNOW that the game's creators have (mostly) kept a secret about one of their products holding a hidden card?
It can be found in a ~mystery spot~ inside The Bigger, Blacker Box, a $15 case that holds all of the game's expansion packs.
When reached by BuzzFeed, a Cards Against Humanity spokesperson wouldn't confirm or deny the card:
"As for your question, there may or may not be a secret card hidden inside the lid of the Bigger Blacker Box," she said. "It's certainly possible there is a secret card hidden inside the lid of the Bigger Blacker Box, but I can neither confirm or deny whether there is or there is not a secret card hidden inside the lid of the Bigger Blacker Box."
