April Fool's Day

Okay, results have been announced and we all know the winner, now can we please focus on something else apart from elections??
let's talk about April fool's day. A friend of mine just tricked me and I fell hook, line and sinker. I wasn't supposed to, and I'm not proud of it since it was the normal message of 'the owner of this phone is sick or in a coma'. But it was as if it was planned cos last night his profile messages were sad cos he was unhappy with the elections and getting a message this morning that he had an heart attack just sealed the deal.
So yeah, I was tricked and I fell, and I've made my excuses as to why I did. Besides I thought April Fool was in the past and no one thought about tricks anymore, but I guess I was wrong.
I wonder how April Fool came about? yeah hold on lemme google it... of course, reception is bad mtchew
