The spark will occur where the gap is narrowest. When air (the dielectric)
breaks down (ionizes) its resistance drops to a low value. This loads down
the voltage, making it impossible for an arc to start up anywhere else. If
you hooked up two spark plugs in parallel, the one with the narrowest gap
would fire and the other one would do nothing.
