Feel like driving someone insane in a malicious way? Come on, everybody knows at least one person they’d like to drive bonkers. This Wrong Number Generator is a brilliantly simple way to do just that.

How’s it work? Well, you plug your victim’s phone into one end and run the other end into the wall jack and leave it to do its business. It’ll then intercept any numbers that they dial and replace them with wrong numbers. This will be annoying. But the real coup? It’ll let the right numbers through 25% of the time, making them think that the problem is with their fat, inaccurate fingers, not with the phone itself. All the while you can sit back knowing that you’re causing lots of stress for your poor victim. Sweet.
