What they said is that it wouldn't have the same appeal, which is true. Someone shooting themselves by looking into the barrel of a gun as a joke is funny because it's a really obviously stupid thing to do. Luke lightsabering himself in the eye is funny first due to shock value, and second as a form of observational humor by pointing out how even though lightsabers are so obviously dangerous, there's not a single mishap where someone maims themselves with their own weapon in the movies.
Someone playing with a screwdriver and a few pieces of various metals is funny because its danger is unintuitive. It's so strange that someone can mishandle such seemingly innocuous objects and then die a few days later because of it, that it's comical. It's a non sequitur.
