I got this in a round robin email.

To fully appreciate it you have to be English, in the middle of a major international football tournament and it helps if you have a healthy disregard for the game too:

New EU directive on road safety;

In order to assist other motorists in identifying potentially dangerous drivers, it is now compulsory for persons who have a lower than average IQ and driving ability to display a warning flag.

The flag (comprising of a red cross on a white background) must be attached to the top of at least one door of their vehicle.

For drivers of exceptionally low ability, additional flags are required.
