Not for the Feint of Heart
As I write this, on April 2, 2016, it's snowing outside. Either someone is playing a leftover April Fools joke or I live in Wisconsin.
Celebrating Play Leftover April Fools Jokes and Pranks Day requires a fair amount of chutzpah.
First, you have to have some jokes or pranks saved up from yesterday that should really only work on April 1.
Second, you should either need to be known as someone who often plays jokes or pranks or you should have friends and acquaintances who won't mind this kind of thing too, too much.
Third, when playing the joke or prank, you need to somehow do it as if it really were April 1 (or at least, make others think that you think it's April 1) or else it's not really an April Fools joke/prank anymore.
Fourth, you should be more nimble than most so you can get out of the way physically or talk you way out of a jam in case those you play the joke/prank on don't care for your sense of humor or aren't aware of what April 2 really exists for.
I don't expect that a lot of you will actually celebrate this day as intended. It feels a little too dangerous, but there might be the hearty soul among you who will give it a shot.
Let us know how that goes...if you are still able later.
