Have a topic pre-selected such as PARTY. Come up with about 20 related items associated with that topic, for example, horn, party hat, favor, balloon, candy, cake, punch, ice cream, music, games, invitations, presents, fireworks, napkins, plates, cups, forks, piñata. Write each item on a slip of paper and as the Scouts arrive, tape a slip with an item on their back (they aren't supposed to see their item). The object of this activity is for each boy to ask questions to determine what they are.
