If you ever find yourself in the mountains of Guerrero during a village festival, don’t be alarmed if you see a man in a jaguar mask leaping at another dressed as a farmer swinging a whip. You haven’t stumbled into a surreal jungle nightmare — you’ve entered the world of the Tlacololeros.

It's called La Noche de los Rábanos — the Night of the Radishes — and it’s exactly what it sounds like… only way stranger.
