His mouth as greet was as a greet forneys.
He was a janglere and a goliardeys.
– Geoffrey Chaucer
The Canterbury Tales, General Prologue. The Miller is said to have a mouth the size of a large furnace (simile). And boy does know how to use it. He is described as a loudmouth and a buffoon. The Miller is portrayed Chaucer as a stereotype of what the author views as the rowdy, bawdy lower social class.
