During the holidays, millions of families sit down to watch classic family holiday movies such as A Charlie Brown Christmas, How the Grinch Stole Christmas, Frosty the Snowman and others that have become part of our popular culture. But what do you really know about these movies? Here is some fun trivia.

Remember the scene in How the Grinch Stole Christmas where the Whos hold hands in a circle and sing? The title of that song is “Fahoo Forays,” and if that doesn’t make any sense to you, it’s because the words are made up. Dr. Seuss invented some of the words of the song and tried to make them sound like classical Latin. Seuss was so successful that some people thought it was real Latin and wrote the studio to ask for a translation.

In A Year Without A Santa Claus, if you look closely when the little girl is writing the word Christmas with a crayon during the Blue Christmas song, you’ll notice that the letters seem to appear before she actually writes them.

The Grinch has blue eyes – but only after his heart grows while he’s standing on the top of Mt. Crumpet. Before that, his eyes are red.

June Foray, who was the voice of little Cindy Lou Who in How the Grinch Stole Christmas, was also the voice of the teacher in Frosty the Snowman and the drummer boy’s mother in The Little Drummer Boy.

In Rudolph the Red-Nosed Reindeer, Hermey is the only elf who doesn’t have pointy ears.

– The only time Lucy ever calls Charlie Brown just “Charlie” in a Peanuts special is just before she discusses the commercialization of Christmas in A Charlie Brown Christmas. Thereafter, she always calls him Charlie Brown .
