For those who don't know what it is: HERE or, simply, someone writes down a list of ending words that rhyme and the poet has to make up a poem using those words in that order. For instance, the rhyme scheme breeze, elephant, squeeze, pant, scant, please, hope, pope are submitted, and the following stanza is the result:
Escaping from the Indian breeze,
The vast, sententious elephant
Through groves of sandal loves to squeeze
And in their fragrant shade to pant;
Although the shelter there be scant,
The vivid odours soothe and please,
And while he yields to dreams of hope,
Adoring beasts surround their Pope.
Each successive poet should provide a new list of words.
