> it's pretty common for a spark to jump the gap of the leads while you're plugging it in

If you’re referring to seeing a spark while plugging something in, that’s just current jumping from the socket to the pin that’s entering it - it’s nowhere near possible for current to jump between the pins on a single plug (in air, at least). The distance between pins was specifically designed to prevent that possibility at the given voltages.

Not saying our plugs aren’t poorly designed, just that that’s not one of their problems.
