Mad Libs books contain short stories on each page with many key words replaced with blanks. Beneath each blank is specified a category, such as "noun", "verb", "place", "celebrity," "Exclamation" or "part of the body". Fill in all the blank spaces appropriately and then the completed story is read aloud. The result is usually comic, surreal and somewhat nonsensical. Lampooning everything from e-mail to the internet to instant messaging to chatting and bulletin boards and beyond. Great for travel. 8+ years.
