“Sesame Street” knows how to use its celebrity guests well, which is probably why Lauren Graham (“Parenthood,” “Gilmore Girls”) gets to explain being an author — with the help of Grover, of course.

Graham is in fact an author in real life, with a book, “Someday, Someday, Maybe: A Novel.” For “Sesame Street,” she and Grover create a new story together. It’s about a dill pickle. After a “terrible deli accident,” the pickle moves home, ending up “living in a tropical fish tank.”

Alas, there is a bit of a controversy toward the end of the video. Grover points out that this book seems to be writing itself — at this point, the book contests authorship.

Will copyright law be included in the next “Sesame Street” video?
