During market day, a wagon's axle breaks and it loses its wheel, setting off a chain of events that culminates in a large scale riot (or at least a pie fight).
 
The challenge: Except for the first sentence and the last sentence, use only spoken dialogue and onomatopoeia (written sound effects).
e.g.:
Rrrrumble...
"Oh heck, get out of the way!"
rumble rumble RUMBLE CRAAASH!! "Mooo-OOO!"
