The Yule goat is a popular Christmas decoration in Scandinavian nations. The two goats in Norse mythology hauled Thor's flying chariot in the same manner as reindeer drive Santa's sleigh. In addition, there's a Christmas story about an unseen Yule goat that checks in on holiday preparations before the big day. As a result, the Gävle Goat was constructed in 1966 in order to attract consumers to the Swedish city where it sits. It is 42.6 feet tall and seven metres long, and weighs a massive 3.6 tonnes.

It's difficult to conceive what you'd want to listen to if you could ever float among the stars. However, the crew of NASA's Gemini 6A space voyage got into the Christmas spirit and created history when they played "Jingle Bells" on December 16, 1965, setting a Guinness World Record for the first music ever played in space. At least, as far as we know...

If you live in Canada and want to become pen pals with Santa Claus, you may use the Canada Post postal system to send him a letter. What is the address? Canada, Santa Claus, North Pole, HOH OHO. And don't be shocked if you receive a letter in return! He has some assistants that keep track of his correspondence.

Today, if you visit Rockefeller Center during the Christmas season, you will undoubtedly be taken aback by the sight of the gleaming tree. According to Time, the enormous tree is illuminated with approximately 25,000 lights each year. Can you picture having to check every light bulb to see if it works?!

Comic Sans, the infamous typeface that appears childish outside of a comic book, is despised by everyone. You'll be surprised to learn that the typeface was inspired primarily by the lettering for Alan Moore's Watchmen and Frank Miller's The Dark Knight Returns.

When Joss Whedon took over production of Justice League after Zack Snyder abruptly left, he had to re-shoot portions of the film. However, for unknown reasons, Henry Cavill was not allowed to shave his moustache. It was part of his image for their Mission Impossible sequel, but was a false stubble really that difficult to create? Producers for the Justice League had to CGI Henry's face and magically remove his moustache. It's a funny time.

Today, it appears obvious that the first superhero was essentially Hercules in blue tights. However, one of the early Superman draught ideas was of a short, bald, mad scientist type who called himself "The Super Man." Perhaps this is why Lex Luthor has such a negative attitude toward super-powered individuals.

DC held a tele-vote in 1988, asking readers to vote on whether Jason Todd should live or die. Todd's abrasive, bratty, and headstrong demeanour made him so unpopular that fans voted "yes," sealing his fate by a razor-thin margin (5,343 – yes, to 5,271 – no). It turns out that The Joker beating him to a pulp with a crowbar and leaving him in an exploding warehouse was entirely up to the fans. Despite this shocking decision, DC continues to pay homage to the iconic character to this day. In fact, an Easter Egg in The Dark Knight featured a small nod to Robin!

Although episodes of SuperFriends show him water-skiing with dolphins, Flash makes it clear in the comics that his ability to control sea life doesn't work as well with them as it does with simple fish. According to this Reddit user, Aquaman can't directly control dolphins because their brains are too developed; instead, he can "influence them and hope they follow his orders."

In the 1940s, everyone's favourite Amazonian was dubbed "Suprema, the Wonder Woman," but editor Sheldon Mayer later dropped the moniker because he thought it was too similar to "Superman." If that isn't shocking enough, consider this Wonder Woman fact: the Amazon Princess and Green Lantern were supposed to be a couple until a fan suggested the same pairing. To avoid legal wranglings, DC decided not to continue with the love story.

Because of their pest-control instincts, a large group of feral cats has been welcomed to stay at Disneyland. You might be able to spot some at the feeding station near the Hungry Bear Restaurant if you're lucky.

Only the Sleeping Beauty castle in Disneyland has a working drawbridge. Only two times in Disney history has the drawbridge been raised: on opening day and after Fantasyland was remodelled.

Cap, it turns out, has the same "problem" as Wolverine in that he is physiologically incapable of getting intoxicated. Unlike Wolverine, who can't get drunk because of his extraordinary healing abilities, Cap can't because of the super-soldier serum implanted into him. Because of the serum, he has an extraordinarily rapid metabolism, which means that whatever alcohol he drinks is quickly burnt off by his system. It's a shame you can't get hammered after a long day of fending off aliens and villains hellbent on taking over the earth.
