There's a whole website seemingly built around this concept - WikiHow : )

It bursts at seams with brilliant "do not say!" type of tutorials - one my favorites is "How to Survive a Coup". Here's some of the advice given by the expert authors (who clearly must have survived a few coups back in the day):

"The most important thing to do during a coup is to stay out of range of gunfire [...] Stay tuned into social media sites like Facebook and Twitter to get regular updates on what is happening [...] If you have television, then you can also try watching your local news channel for updates [...] Leave the country or go to a safer region if the conflict continues"

So remember, try staying out of range of gunfire and don't forget to subscribe, everyone
