Each person adds 3 words per post to a story in order to continue the story. This game is basically an improv game where you start a story with three words, and the next person continues with the next three words of the story. For example:
Mary: Johnny ate a
Joe: big fat dog
Tim: and he threw
You can end the sentence if you want, and start a new one, but you MUST only use 3 words.
Some basic rules: Each person cannot post back-to-back, but must wait for someone else to post before he can reply. No lewd or inappropriate words.
