Oh, the things you can do with a little creativity and a couple USB ports. The “Crunching Dogs” USB gadgets workout, tirelessly doing ab crunches while plugged in to your computer’s USB port.

Of all the USB gadgets I’ve seen, including coffee warmers and mini-vacuum cleaners, I think the “Crunching Dogs” have the most personality- by far. But, according to Coolest-Gadgets, these little guys have no on/off switch, so you may have to eventually pull the plug on them if you want to get any work done. However, I bet everyone at the office will somehow be jealous of these four-legged USB accessories, even if they occasionally get annoying. These USB dogs are available at Think Geek for $9.99 each.
