The "remain calm" iconography on this emergency sign in Mexico is the best thing ever.
@everywhereist I was a first-time visitor to México D.F. when a really minor quake (a 4.9 if memory serves?) struck.
The automated message intoning "¡Mantenga la calma! ¡Mantenga la calma!" was, um, not very calming to my gringo nerves. 🙂
(The locals had a good laugh at my expense, though!)
