This is a game of poetry. Basically, the first person takes any first line of a poem, and the second person has to finish it with a line corresponding in rhyme, measure, and sense with it. Humor is optional, but definitely wanted.
An example:
There is a garden is her face;
A silly second line would be,
Her dermatologist has the case.
Anyway, post a finisher to the line ahead, and post a new line for the next player.
"I strove with none; for none was worth my strife"
Let those creative juices flow!
