You've never heard of putting a penny into an Edison base fuse socket then screwing the blown fuse back in?

The penny contacts the center contact in the fuse base and contacts the screw shell, thereby making contact across the fuse holder as though the fuse was not even there (you can pass a heck of a lot of current through a copper penny before it melts). The fuse only holds the penny in place, heck, you could take the shell from a light bulb (lamp) and screw that in to hold the penny in place.
