Why is an electric cord with two plug end (and no ‘outlet’ end) so cursed and could it have a use even if it’s kind of pointless?

Answer 1

These are extremely common around the holidays and have to do with stringing up Christmas lights. I used to work in a hardware store and we’ve had people come in looking for them.

Essentially, the idea is to combine two sets of lights that were run incorrectly and connecting them via the female (holed) sides of both strands of light. In theory, you would think it works; in practice it will either shock the hell out of you, burn your house down, or both.
