Explanation:

In Geoffrey Chaucer's "Canterbury Tales", the tale told by the Pardoner revolves around a group of rioters. They did nothing except drink and reveling. The Pardoner's Tale discusses the issue of gluttony, pride and greed and drunkenness.

In the tale, the three rioters had learned from a servant of one of their friends that his relative had been killed by Death. In their drunken stupor and anger, they went looking for the person responsible for the death. They planned on avenging the death of their friend. This tale about the rioters is on the theme of drunkenness and gluttony, the very sins that the pardoner is working against.
