April Fools' Day is an annual celebration in the U.K, Europe and some other western countries commemorated on 1st April each year by playing practical jokes and spreading hoaxes. The theme of left-handedness has been incorporated into this by some companies in recent years, based on promoting a “left-handed” version of something that clearly has no possible handedness, like a hamburger!
The origin of April Fools' Day, also know as All Fools' Day, is uncertain but it seems to have been celebrated in Britain and other parts of Northern Europe since at least the 18th century.
Here is a good example of a business “left-handed” April Fool joke:
The Left-Handed Sandwich
UK bakery chain Sayers announced the launch of a new “left-handed sandwich” designed to fit more comfortably in the left hand and result in fewer embarrassing “spills.”
All the ingredients in the left-handed sandwich had been rotated 180 degrees in order to redistribute the weight of the sandwich, so that the bulk of them skewed to the left. The packaging was also altered so that the door opened to the left.
The company's Head Sandwich maker said: “Depending on how well the left-handed sandwich goes down we may look at mirroring this across our whole range and producing left-handed doughnuts.”
