(Fucking salt lamps, really? I knew people were stupid, but come on)
One of my neighbors got a salt lamp for Christmas and put it on the curb for garbage pickup by New Year's Eve. I saw it when I was walking the dog and snatched it up. I was hoping to wrap it again and re-gift it to someone as a gag, but my wife saw it and plugged it in. Now it sits as a night light on the counter in the hallway going to the bathroom. True story.
I don't know about any health benefits, but it is strangely attractive. A light bulb inside a lump of salt. Who would've thunk it?
