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. A Mad Libs featuring 21 original stories all about school and every kid’s worst nightmare - being stuck in detention! Great for travel. 8+ years.
