17627 Humptydumpty           Discovered 1996 Jan. 27 by T. Urata at the Nihondaira Observatory.
Humpty Dumpty, whose head and body together are egg-shaped, is not only the subject of one of the most famous nursery rhymes in English but also a major character in Lewis Carroll's Alice's adventures in Wonderland. He tells Alice a lot about the meaning of words, including the strange ones in the poem "Jabberwocky".
