An easy enough venture to comprehend. Simply add 3 words in some coherent fashion to complement the previous posters words.
Example:

There once was....
a little girl....
who would always....
etc. etc. No storyline or plot needed. As long as the sentences make sense. And remember, only 3 words. One letter words count such as 'I'and 'a'. It's alot better when you aim to make a story out of it but do keep it civil and not retarded. If you're going to try to be funny, make sure it is first.
To avoid confusion on whether a sentence is finished, place a period at the end of a finished sentence. Use commas also where neccesary to avoid more confusion. I'd hate to be a grammar nazi but it helps the person after you try to see where you're coming from.
Also if you're going to reply with more then just the 3 added words, be sure to enclose the 3 words in the [ code ] tag.
Here we go...
