This, of course, reminds me of the joke about the different measurement systems:

There are two types of the countries... those who use metric and those who have been to the moon.

Waffle House Index

How bad is a given situation? Use the Waffle House Index:

Green means the restaurant is serving a full menu, a signal that damage in an area is limited and the lights are on. Yellow means a limited menu, indicating power from a generator, at best, and low food supplies. Red means the restaurant is closed, a sign of severe damage in the area or unsafe conditions."
