I'm curious where the line gets drawn on this. I mean, yes given the context of April 1st and the nature of the text it was clearly a joke.

But what if you removed either piece of that? What if they'd done this same announcement on the 3rd wed. of October? What if they'd sent out announcements, rented a convention center, setup a "One More Thing" reveal? Then a couple days later admitted it was a joke. Pretty epic prank really. In many ways, much much more funny. Also pretty clearly illegal.

What if on April 1st they announced something that was so drastic that people thought it was an April 1st joke but it wasn't?
