Back in WWII, when the UK was being pounded by daily barrages of high-explosive, the government's message to the people was Keep Calm and Carry On. Not "ZOMG TERRISTS GONNA KILL US ALL ZOMG ZOMG ALERT LEVEL BLOODRED RUN RUN TAKE OFF YOUR SHOES MOISTURE BOMBS ZOMG!"

Now you can get it on a shirt, and remember a time when governments tried to keep us safe by making us secure, instead of scaring the shit out of us.
