We’ve all heard about the USB Humping Dog and we’ve all had a good chuckle over the quasi-procreating ways of our canine friend, but isn’t it about time that he learned a new trick? I’m not sure if this is any more work safe than the humping dog, but the puppy has now learned a new move that is still being powered by a USB port.

The cleaner-minded amongst us will say that this new dog is simply performing a series of sit-ups, perhaps trying to motivate you to hit the gym and lose that spare tire around your waist. The dirtier-minded will assume that the USB Humping Dog has simply picked up a copy of Kama Sutra and is experimenting with different positions.

Yes, Fido is just as useless as he’s ever been, but now he’s also proven that he knows more than one trick. I’d hate to see what will be coming next in the USB Dog series. Pick him up, if you dare, for $14.
