World s Greatest Word Game is sure to keep kids (and adults) laughing for hours. Players call out their ideas to fill in the blanks with parts of speech (verbs, nouns, adjectives and adverbs) and you end up with a story reeling from one silly sentence to another until nothing makes sense. That’s what you call a Mad Lib and both adults and children have been howling with friends or laughing all to themselves for over 35 years!
