Player One creates a sentence that uses an adverb. Player Two repeats the
first sentence replacing the adverb with another appropriate describing word.
Player Two then creates a new sentence that passes to Player Three.
Player Three replaces the adverb in Player Two's sentence and creates a new
sentence.
Example:
Player One: I saw a dog jump excitedly over a fence.
Player Two: I saw a dog jump lazily over a fence. The clerk bagged the
groceries listlessly.
Player Three: The clerk bagged the groceries cheerfully. The pig ate
greedily.
