The Monster at the End of This Book

This is Morning Edition from NPR News. I am lovable for you, Cal Grover. I'm Ian Martinez. And I'm Steve Inskeep. Our cohost there is a Muppet from Sesame Street. Grover, like NPR, is celebrating a 50th anniversary. Oh my goodness. Well, happy birthday to NPR. But in Grover's case, this is for the classic children's book, The Monster at the End of This Book. It's a fabulous classic children's book that basically breaks the wall to the reader, to children. And from what I understand, it's the first time it has happened with a children's book. This book was published in 1971, where Grover is speaking to the reader saying, don't go to the end of this book. There's a monster. Don't do it. He's building brick walls. He's doing whatever he can to convince the child reading, don't go there. And he warns us this morning, I'm sorry for our young listeners, spoiler alert, he's the monster.
