The classic children's book Where the Wild Things Are, written by Maurice Sendak, celebrated its 50th anniversary on Saturday.
The book, about a little boy dressed up in a wolf suit who tells his mother, "I'll eat you up!" and is sent to his room without dinner, came out in 1963.
USA Today reports that bookstores across the nation hosted parties with the theme of "Wild things" in honor of the book. HarperCollins, publisher of the book, issued an anniversary edition, complete with Sendak's illustrations with the original colors he used.
Last year, the Library Journal asked readers what their all-time favorite picture book was - Where the Wild Things Are won by a landslide. The book, just 350 words, has topped other best-seller lists as well, selling over 20 million copies in 32 languages.
In 2009, Spike Jonze created a film adaptation for the story.
Sendak roared his terrible roar and gnashed his terrible teeth for the last time last year when he died at age 83.
According to the Washington Post, HarperCollins senior executive editor Toni Markiert revealed that the book's original working title was "Where the Wild Horses Are," but after Sendak gave up on trying to draw horses, he said that all he could draw was "things."
