Common knowledge. You know, the sort of stuff you’re supposed to learn in the school of life—like don’t put your tongue on the flagpole in December. Uncommon knowledge, on the other hand, is a more elusive matter. It’s the kind of facts that might make you lose a little sleep wondering why, how, or even what the heck? Our designs often inspire such tantalizing trivia and these Uncommon Knowledge highlights illustrate those quirky connections. And to keep things extra-uncommon, we’ve added a fresh batch of bonus facts. With this uncommon knowledge in mind, any of these goods are conversation-starters.

Where Did the Silhouette Get its Name?

But before you accuse us of spreading “fake news,” we must admit this study is just and elaborate dad joke…

Who Invented the Hashtag?
Familiar to Twitter users everywhere, the pound sign or hashtag (#) has a pre-social media history. In fact, it has a prehistoric history. 39,000 years ago, Neanderthals were trending. This upcycled hashtag pin is a retweetable way to celebrate the storied symbol. Read more >
Extra-uncommon knowledge: “Neanderthal” has long been shorthand for dumb and unsophisticated, thanks to the conventional notion that Neanderthals were intellectually inferior to their Homo sapiens cousins. Recent research suggests otherwise, asserting that Neanderthals were expert hunters, planners, and team players. So why did they die off? Inbreeding is now the frontrunner rather than death-by-hominid-competition.
Why Does That Little Star Twinkle Twinkle?

Extra-uncommon knowledge: To date, astronomers have detected more than 3,500 exoplanets (planets outside our solar system).

Who Put the Cod in Codswallop?
“A load of codswallop!” A colorful, colloquial phrase with an equally quirky backstory. Could be that it’s based on bottles by Hiram Codd filled with cheap beer.

Extra-uncommon knowledge: By and large, beer is a vegan beverage—but there’s something fishy about Guinness stout. Until recently, all Guinness contained isinglass, a collagen derived from fish swim bladders. Eww. The substance helps extract spent yeast from the beer to clarify it, a process known as “finning.” Vegan Guinness drinkers cried “codswallop!” and convinced the brewer to begin removing isinglass from their beer. As of this writing, it’s unclear whether that process is complete (they targeted 2016), but Australian-brewed Guinness at least is now fish-free.
