Marvin K. Mooney Will You Please Go Now! is a 1972 children's book by Dr. Seuss. Written as a book for early beginning readers, it is suitable for children who can not yet read at the level of more advanced beginning books such as The Cat in the Hat. The book presents, in short and funny fashion, Dr. Seuss's nonsensical words, rhymes, and illustrations. It is not entirely clear what the story is about but is known to have a similar ending to Green Eggs and Ham. One popular interpretation of the story, given Marvin is wearing purple pajamas, is that he is being told to go to bed by his parent, though the story was designed to be ambiguous in nature.
