I read this in Middle English, so it was extremely challenging, but well worth the extra effort. The "Canturbury Tales" are a collection of stories, all but two of which, were written in verse. In the framing story, 24 pilgrims are on their way from Southwark to Canturbury to visit the Saint Thomas Becket shrine at Canturbury Cathedral. When they stop along the way, they entertain the group with tales, some serious, some hilarious, some racy, some satirical, and some laced with religious themes. The most famous of these is "The Knight's Tale," in which two friends, both knights, fall in love with the same woman. The funniest and bawdiest story is "The Miller's Tale," which includes extramarital sex, ass (ers) kissing, and farting! I'd highly recommend at least attempting to read the book in its original language, as the verses are incredibly beautiful and well-written. There are several versions that include either glossaries or interlinear translation which is necessary to fully understand the meaning of the text, but a strictly modern version will miss much of what makes Chaucer amazing.
