"Mr. Nobody" is an anonymous poem for children that talks about the nature of responsibility. The poem is written in eight line stanzas rhymed abcbdefe and is written in lines of alternating iambic tetrameter and trimeter. The poem lists a group of the typical minor peccadillos committed by young children.
Mr. Nobody is described as being responsible for all forms of mischief and mishaps in daily life, such as cracking plates, damaging books, losing buttons from shirts, tracking mud into the house, and other similar minor forms of misbehavior.
At the beginning of the poem, Mr. Nobody is described as odd and quiet; the narrator adds that no one ever has seen him. This and his name tell us that Mr. Nobody doesn't actually exist; instead the poem gently makes fun of children, who an being asked who tracked in the mud or forgot to lock the door, answer "nobody" or refuse to admit that they are the culprits.
