Ahh I miss the time when we were making des petits poissons in class to stick on the back of others *giggles like a little girl*
Here in the UK the tradition requires the joke to be played before midday, passed that time you become the April Fool ('April Fool's Day is past and gone, You're the fool and I am none'), which is a bit silly let's be honest. I mean come on it's only one day in the year and you only get half a day here, just enough time to cut all ur fish. In France, we are big jokers and the poisson d'avril (April's Fish) jokes may last aaaall day. Apparently (a little bit of history here), the term "poisson d'avril" comes from the fact that in April the sun quits the zodiacal sign of the fish.
I can't remember making much pranks as a kid, some, but not a lot because the beauty of April 1st really has always been trying to attach a paper fish to someone's back without, of course, being noticed.
Tout un art my friend ... and I don't want to bribe but I was very good at that
