Monster in a Box

Monster in a Box is a monologue originally performed live on stage by the writer Spalding Gray then subsequently made into a 1992 film starring Gray and directed by Nick Broomfield.
A follow-up to Gray's earlier work, "Swimming to Cambodia", the work consists of a long-form monologue by Gray detailing the trials and tribulations he encountered while writing his first novel, "Impossible Vacation" (the titular "monster"). The soundtrack for the film was composed by Laurie Anderson.
An extended version of the monologue was published in book form prior to the release of the film.
Parody.
This monologue – or at least its title – was parodied on "Sesame Street" in an installment of "Monsterpiece Theater." The main actor (and writer) for the parody was a monster aptly called Spalding Monster in homage to Gray.
