USB Pet Rock
The original Pet Rock fad from the '70s may have faded away (they should still be alive though), but now in the 21st century, ordinary rocks have been genetically mutated and crossbred with the latest technology to create the ultimate compatible stone, the USB Pet Rock. When your rock arrives in its well, ventilated box, just remove, hug, and attach its built-in umbilical USB cable to your PC or Mac... and, well, that's it! It doesn't actually do anything! Cool huh?
