Ultimate Prank On Humanity...

[Souldemon8]

Let's say it was April 1st and through some means you have been granted with an infinite amount of funds what would be your ultimate plan to troll humanity?

 

[Palfreyfish]

Clingfilm over ALL the toilets. Or draw dicks on ALL the things.

 

[Terminate421]

The first thing anyone opens up in their computer is Rick roll.

 

[aegix drakan_v1legacy]

Make all the stock market screens and news channels all over the world show Tetris gameplay for 24 straight hours.

EDIT:

Fake a whole alien landing and making first contact with them.

Or this. This would be hilarious too. XD

 

[Scarim Coral]

Fake a whole alien landing and making first contact with them.

 

[AngleWyrm]

Develop and deploy Cylons throughout the planet.

 

[OneCatch]

Fake a whole alien landing and making first contact with them.

Or, you use cloudbursting and airborne lasers to write:

"THIS IS XENU - WHY DIDN'T YOU LISTEN TO L RON HUBBARD?"

in the clouds, over every country, in every language.

 

[Hal10k]

Create a perfectly accurate calender designed to be perfectly accurate throughout thousands of years, then abruptly stop on some random date.

 

[The Rogue Wolf]

Whoopie cushions.

Billions and billions of whoopie cushions.

And then, an elaborate ruse to get everyone on the planet to sit down at exactly the same time.

 

[CM156_v1legacy]

Whoopie cushions.

Billions and billions of whoopie cushions.

And then, an elaborate ruse to get everyone on the planet to sit down at exactly the same time.

Yeah, but if everyone did it at the same time, I don't think it would be as funny.

Though I do agree with you. Billions and billions of dollars in whoopie cushions

 

[Megawat22]

Convince an entire city that they're dreaming and then have it all filmed.
It'll either be hilarious or just awful, but I'm willing to take that hypothetical chance.
Just imagine the headlines the next day "Billions of puppies adopted in *insert city here*. Also hundreds of counts of public nudity".

 

[OneCatch]

Create a perfectly accurate calender designed to be perfectly accurate throughout thousands of years, then abruptly stop on some random date.

I see what you did there!

 

[Heronblade]

Stage an incident that makes everyone think that Odin is real, just got back from a long vacation, and is drunk off his nordic arse.

 

[Black Arrow Officer]

Stage a fake coup of the American government by ponies.
