Update May 8, 2012: Maurice Sendak died at the age of 83 in Danbury, Connecticut, the Associated Press reported. He painted a mischievous dreamscape in his books, fraught with tension and the “humongous heroism of children.” Read his obituary here and watch Sendak in his witty prime below.

Original post:

Maurice Sendak, children’s literature’s favorite curmudgeon, looked awfully annoyed on the Colbert Report on Tuesday night.

Sendak’s three grouchiest quotes:

• “Newt Gingrich is an idiot of great renown.”

• On children: “I like them as few and far between as I like adults.”

• On Colbert’s idea for a sequel to “Where the Wild Things Are:” “It is so bad that it not only will sell, but it will make pots and pots of money for you.”

Someone’s having a no-good, very bad day.

Update: Here’s part 2 of the Sendak interview. Some Post readers took issue with this blog’s playful characterization of Sendak as a grouch. For the record, we knew the author had a good sense of humor.
