Seriously, do it. See what happens.
Despite my personal aversion to the “Keep Calm and Carry On” memes, they do have quite the interesting origin.
“Keep Calm and Carry On,” is a catchphrase from a WWII British safety poster that was commissioned in 1939 by the provisional Ministry of Information in England following two other inspirational posters including “Freedom Is In Peril, Defend It With All Your Might” and “Your Courage, Your Cheerfulness, Your Resolution Will Bring Us Victory.” After one of the few original posters was miraculously recovered and placed in a British bookshop in 2000, the motivational message was shared online and ended up inspiring a series of memes that have taken over the internet and t-shirts all over the globe.
