Everyone probably knows how this game works already, but for those who don't:
The card czar shows a black card. Everyone else has a selection of multiple white cards. The black card typically has a question to be answered or a blank that you have to fill. The user-selected white card is used to fill in the blank. A white card usually has witty humor or straight up love jokes. The card czar picks one of the user-selected cards that they find the best, and whoever chose the card is awarded a point.
It goes no further from just picking the funny white card.
