HERE to go to the source. How cool is that!
To play the game, you have a group of people sitting around one of the game boards. Play one candy on each character on the board (there are two boards pictured above). One person leaves the room and the rest of the people choose one of the characters to call "Frank." The person rejoins the group and takes a candy off of each character until he gets to the one that the group chose to be "Frank." When the person goes to grab the "Frank" candy, everyone yells, "DON'T EAT FRANK!" and the person's turn is over. Repeat process with people taking turns leaving the room and picking different characters on the board. This game is a hit for people of all ages. I've read of a fun rule that says if the guesser picks the "Frank" on the first guess, then they get to keep all the candies on the board. Sounds like fun to me!
