Morlock

Morlocks are a fictional race of subterranean creatures.

History
While attached to a bungee cord, Homer and Otto descend into the sewers and briefly encounter a group of Morlocks.

When Homer told his friends at Moe's a story about Bart digging a hole, Moe interrupted Homer and asked him if his story was going anywhere. Homer told him "yes", and went on to say that eventually he became "king of the Morlocks". Carl told Homer that that couldn't have happened because Morlocks are from the future, to which Homer angrily responded "Are you calling me liar?"
