This game goes typically goes by a different name when adults play, and it's been known to include alcoholic beverages as well. Luckily, there's a family-friendly version called "I Doubt It," and there are no shot glasses involved. Deal five or seven cards to the each player -- you can have anywhere from three to six players. The designated lead player names the first rank, the suit does not matter. Then, go clockwise around the table, with each player either passing if he or she doesn't have the named rank, or laying a card faced down on the table. Play for each round continues until all players pass or there's a challenge. If you feel like your little brother is trying to fool you, smack the deck and declare "I doubt it!" Turn the card over -- if it's not the designated rank, the bluffing player picks up all the cards and the challenger names the new card rank. If it is, the challenger picks up the cards and the one in doubt takes the lead. The winner is the first player to get rid of his or her entire hand.
