Oh, brother. As we all know so well, the office can be a draining place. But devices such as these could make even the most burnt-out middle manager excited to clock in. The USB
PC Prankster looks like a stock flash drive, but as you can clearly see above, a few toggle switches enable it to become quite the headache. Once plugged in, the unlucky PC that it's attached to will have its Caps Lock enabled and disabled at random, see garbled text splattered about quarterly reports and be victim to uncontrollable, erratic cursor movements. Thankfully, the drive will never activate the Enter key nor close or save documents, so you can rest assured that it's all in good fun. Turning your office up on its head costs just £19.99 ($33), but you'll have to wait a tick 'til it comes back in stock.
