Some points regarding humor in The Nun's Priest's Tale by Chaucer:
There’s an episode of the show 30 Rock in which Tracy Morgan’s character hopes to win a Golden Globe for his new movie Hard to Watch. The title of the fictional movie is poking fun at the lamentable fact that many of the movies that win today’s most prestigious awards are painful experiences for viewers. The difficulty or impossibility of enjoying these hard-to-watch movies seems to be taken as evidence of their artistic merit. This seems to be precisely wrong: the best art should be joyful, should make us happy, and should be easy to watch even if hard to fully understand or appreciate.
