Heh. I remember that. We plugged the floppy in backwards and turned
the machine on. A few moments later, the smell of smoke flowed from the
open case.

Yeah. For a circuit to be complete, some resistance must exist; simply
hooking the two poles of a power source together won't wield anything
too incredible, nor will putting LEDs down without resistors produce
anything more than a moderately warm battery.
Oh, and to any of you who've noticed, this is why resistors are needed
along with LEDs since LEDs don't provide their own resistance.
