Any Suggestions?

My husband received this dollar bill as change from a purchase. Initially I thought someone had just been scribbling random words and sentences on the back, but as I read it I found a sort of rhythm. To me at any rate each successive clause/phrase seems weaker than the last, and I came to the conclusion that a wouldbe writer of a rap song did not have any paper handy. Pretty impressive pen though. I know nothing about rap and have been trying to come up with a fourth line. Are there rules? I am pretty sure it is not supposed to follow the structure of a sonnet.

Any suggestions?
