TODAY (April 1) is celebrated across the world as April Fools' Day or All Fools' Day.

The traditional holiday celebrated in many countries with practical jokes on friends, family and colleagues. The aim of these hoaxes is to embarrass gullible people into believing them.

In the UK these jokes only last until noon, and someone who plays a trick after noon is called an April Fool.

One of the earliest references to April Fools' Day is in Chaucer's Canterbury Tales dated to 1392.
