He's a mean one, Mr. Grinch, but you can save Christmas, simply by defeating this trivia quiz! You'll have to know all there is to know about How the Grinch Stole Christmas: the story, the cartoon, the live-action movie [2], and the music. Only know one of the above by heart? You'd better hope you're lucky.

Before you pour yourself another cup of cocoa, put on your Grinch pajamas [3], grab your stuffed Grinches [4], and show this quiz who's boss. The Whos down in Whoville are all counting on you!
