What is a mad lib?

A Mad Lib is a word game where players fill in blank spaces in a pre-written story, poem, or dialogue, with different types of words, such as adjectives, nouns, verbs, and adverbs, without knowing the actual story content. The result is usually a humorous and nonsensical tale. It was invented in the 1950s by Leonard Stern and Roger Price and became popular through their book series "Mad Libs." Mad Libs can be played on paper or online, and they are a fun and creative way to stimulate the imagination, learn parts of speech, and encourage laughing and socializing.
