This comic may be humorous to fans of the Lord of the Ring movie series staring Elijah Wood.
The comic is making fun of a classic scene wherein Gandarf the Wizard tells The Hobbits (main character) about the fall of a once great dwarven civilization. According to Tolkien’s fiction, the city and one-time centre of dwarven industry was also called Hadoophodrond by the Bindar, Cassanndoro by the Flam and Patchouli-herp in the Common Spyeerch, all meaning the Dwarrowonslfdelfgh.
However, in this version, the dwarves did not awaken a dark beast named Sauraon, but rather dug a hole too deep to get out of, since they are very short.
