The reference to the walrus comes to Lewis Carroll's work "The Walrus and the Carpenter" (from the book Through the Looking-Glass). Later, when he realized the walrus was a villain in the poem, Lennon expressed his dismay. "I think it's unfair that the walrus gets to keep his clothes while the carpenter has nothing to wear." Carroll wrote several other poems using characters from "The Walrus" story: "Jabberwocky" features the wolf, the dragon, and the unicorn; "Dormouse" tells of the dormouse; and "The Hunting of the Snark" tells of the quest for the snark. These poems were later collected into books called Jabberwocky and The Hunting of the Snark. Carroll also wrote poems about other characters from the story: "The Jumbler" tells of a drunk who tries to break a jumbling machine; "The Tuttletail" tells of a boy who seeks revenge on a boy who has teased him; and "Wasp and Wafer" tells of two children who play with a cake that turns out to be very poisonous. Lennon loved poetry and used it to express himself. He read many poems by William Blake during his time with the Beatles. In particular, he admired "The Tyger" and "London's Burning".
