From the "are you f'ing kidding me?!" department comes the mouse jiggler, perhaps the dumbest and most useless computer peripheral I have ever seen. And that's saying a lot, as my job is basically to find and make fun of useless computer peripherals every single day. This thing doesn't have the charm of the USB Dolphin Mousepad or the sassiness of the lit-up internal computer fans. No, the Mouse Jiggler is just pure idiocy.

What is it, you ask? Well, it's a $30 USB dongle that nudges your mouse around so the screen saver doesn't come on. That's it. Yes, you can change the settings on your computer so the screen saver comes on after more time or not at all, and it's free. But why go through 10 seconds of mouse clicks when you could waste $30 on a stupid product such as this? Buying things makes you happy!
