The day of the year when the trolls of the world run a muck on the poor, helpless saps known as "citizens." The date is April 1st, also known as April Fools Day.
I'm staying away from my computer tomorrow. It's National Troll Day and I know there'll be something waiting on me.

I have this huge joke that I'm going to pull on my room mate, but I'm going to wait for National Troll Day to do it justice.
