-Whatever comes up during the day, you can amuse your friends by asking a riddle about it—eating, studying for a test, going to the mall, watching TV, or playing with a pet. Sports, animals, music: everything's an opportunity to show off how clever you are. What are the smartest insects? Spelling bees. What do astronomers sing in the shower? When You Wash Upon a Star. These and hundreds more mean hours of laughs!
