April Fool’s Day... The origins of this “holiday” are not certain, but there are many theories. One of these claims that when Charles IX of France moved the beginning of the year from April 1 to January 1 by decree in 1564, those who refused to adapt were called “April Fools” and were the target of derision and practical jokes. Traditionally, in France, children try to pin paper fish to the backs of unsuspecting victims; once the recipients notice, they are greeted with gleeful cries of “Poisson d’Avril” (April fish). The same expression accompanies any other prank at the moment the hoax is revealed. Why fish? Nobody knows for sure, but in France, they are the symbol of the day, as shown by this colorful duo caught in the company restaurant earlier today.
