"Jabberwocky" was a poem by Lewis Carroll, published as part of Carroll's Through the Looking-Glass. The poem was about a boy killing a monster, and contained a lot of nonsense words.

While working on Bessie, the Third Doctor sang the first few lines of Jabberwocky. (TV: Doctor Who and the Silurians)

During his confrontation with Light, the Seventh Doctor mentioned bandersnatches and slithy toves. (TV: Ghost Light)

The Doctor loved the words "burbled" and "tulgy", which originated from the poem and which he thought were good for describing woods and puddings. (PROSE: The Nightmare of Black Island)

In 1989, Heather Lake helped her young daughter Annabel read the poem. (COMIC: The Broken Man)
