The sprites' contribution to great literature is to come up with limericks on a regular basis. The sprites don't attempt to be subtle but then a great limerick isn't either so this probably is a match made in heaven. They are also fond of adding captions to the tags explaining what pictures are what in the Kingdom galleries. This can go down well, most of the additional captions are amusing, but the curators have sworn to hunt down and punish severely those doing this kind of thing.
Some comedy programmes from Earth are directly imported and watched. Others are adopted for use in the Kingdom. Occasionally the Kingdom tunes into a live comedy show from Earth if they like the look of the comic. Humorous books are a relatively new development. These tend to come out published by folk like Hanastrew, who is developing a humorous version of the Kingdom's highway code.
