True trivia that may break a few hearts: when the Joker first appeared in 1940, he was supposed to be a one-off event that would disappear after a few incidents.

We would never have spotted these amazing Easter Eggs in the latest Joker film if it hadn't been for the internet!

Knowing that there was a "year without summer" two centuries ago can make you enjoy our pleasant, bright weather a little more, according to USA Today.

Bob Kane created Batman, but it was collaborator Bill Finger who added numerous essential elements that helped him become the iconic hero we know today, such as naming Gotham City, naming him Bruce Wayne, and completely revamping the original costume (a red bodystocking with a domino mask) with pointed ears, a black colour scheme, and a scalloped cape. Yet it wasn't until recently that DC Comics began crediting Finger as a co-creator.

The young queen was a wedding trendsetter. In 1840, it wasn’t normal to see a bride wearing white. The color was considered boring and conservative, but Victoria didn’t care. She chose simplicity over opulence, and her lacy silk-satin grown—crafted from the finest British textiles—gave a much-needed boost to the struggling lace trade. Several years later, a women’s publication stated that white was the “most fitting hue” for brides, and a tradition was born.

While there are many fanciful elements in the way mobile suits function, such as the Minovsky Particles that fuel them, most of the technology is based on true science.

Back in the 10th century, carrots were originally white, purple, or pale yellow. So how did they get their distinct orange colour? The story goes that when William of Orange (King William III) helped the Dutch win independence from Spain in the 17th century, Dutch farmers honoured the King by turning their carrots orange through clever breeding. The new colour became hugely popular and is still the Netherlands official colour and the colour of the Dutch Royal family. The Dutch celebrate King’s Day by wearing orange and even the national sports teams wear orange.

While it's become incredibly common and is not considered a serious sin now, one prominent Catholic, mathematician Aquila Ponticus, was excommunicated from the church in 120 A.D. for practicing astrology.
