Our favorite April Fools’ tradition is the French Poisson d’Avril (April fish), where you are supposed to go around taping paper fish on the backs of friends and acquaintances. We learned that Italy has their own version of this holiday, Il Pesce d’Aprile! However, in both countries, the “fish” means the appearance of fish-shaped chocolate as well. Of course we approve of any holiday where chocolate eating is sanctioned.
