Being an Anon isn't always easy. Put my head on the pillow last night and this popped into my thoughts. Putting something on a shelf, shelving something means to put it away for a while - stop doing it. "The discussion was shelved" is an example. So what if Elf on a shelf was not just about finding the elf, but was also about putting an end to something. Then I thought about whether or not ELF could be an acronym for a weapon or system that has been 'shelved'. Just now I looked up Extra Low Energy - (it's actually Extremely Low Energy) and yes, it's a thing. What caught my eye was this snippet from wiki…"ELF waves can also travel considerable distances through "lossy" media like earth and seawater, which would absorb or reflect higher frequency radio waves." Have there been anymore global EQs since Elf on a Shelf popped up?
