The Original #1 Mad Libs

The official publisher's description of The Original #1 Mad Libs outlines a simple word game concept:
• How it works: One player (the narrator) asks another player to supply specific parts of speech—such as a noun, verb, adjective, or adverb—without showing them the story text.
• Definitions included: The books provide quick definitions and examples of parts of speech to help players remember them.
• The result: The requested words are plugged into blank spaces throughout a short story, song, or letter, turning the text into a silly, nonsensical sequence.
• History: The game was created in 1953 by comedy writers Roger Price and Leonard Stern, and first self-published in 1958
