Many are known as "pocket gophers". I was envisioning a future where right thinking people could carry them around for protection in case they were accosted by ruffians and hoodlums such as Al Fansome and his ilk.
I can see it now, the victim shouts, "Fire Chip! Fire Dale!", and the bad guys flee for their sake of their ankles.
Remember kids, stray gophers cause a lot less damage than stray bullets.
