A search on YT for 'canterbury tales rap' turns up about a hundred results; mostly aging English teachers trying to be hip. But this is the best one; you can tell these guys really know what they're saying, and put the rhythm of the poem well to a rap beat. More than that, their pronunciation is excellent.
If you haven't read any Chaucer and lack the incentive, let me provide you with some: a few of the Canterbury Tales are absolutely filthy, even by internet standards. Stuff ranging from anallingus to St Paul going around magically covering people's entire bodies with penises. And contrary to internet standards, they're almost always funny. Look up the Miller's Tale for a start.
