1st of april or Poisson d'avril!

So, spring is here and in various countries they have weird ways to celebrate it.
In Greece, where I come from, we try to fool someone by saying a harmless lie. Being a person that I despise people that tell lies, the least to say, I do not like much this custom....
In France, where I actually live, that make "poisson d'avril" (april's fish) and kids try to fool someone by sticking a paper-fish in their back. I prefer this custom by far, not to say that I really enjoy it :)
Give me feedback from your country customs from 1st of April to change a bit from cooking today.
May a productive month is waiting ahead!

P.S: Fish generously provided by my personal artists, my kids ;)
