I read this in the 8th grade, and I didn't think it was funny. Now that I can understand it, it is "humorous" in a very crude way. Of course, one could say that of the Comedy Channel also.

what is funny about the summoner's tale

The key to the "humor" is in satire. The Summoners Tale is a reply to the Friar's Tale. Both are corrupt and both are accusing one another of corruption. There is a lot of satire in Chaucer's Tales.
