The Reddit /r/electricians recently had a post of a sign at Ace hardware showing a male-to-male adapter for Christmas lights, saying "This adapter does not exist, please don't ask us for it, it's illegal, it means you hung your lights wrong and you need to re-hang them. Sorry."
Comments included: "I worked at a store and every year we'd get someone insisting they bought such an adapter the previous year", "such an adapter would leave energized bare prongs at the other end", and (relevent to this discussion) "the fuse would be at the wrong end of the string of lights".
And, of course, all sorts of comments about homemade adapters, generators being used with such adapters to energize circuits during power outages, etc...
