Lawn forking, what kind of prank is that???

I've lived in the states my whole life, but I've never heard of putting a ton of plastic forks on a law in the middle of the night as a thing, these guys are weird.

I mean egging ot toilet papering a place, years sure on Halloween, but that one no. I mean I'm all for random pranks but has anyone else ever seen or done that, or is it a New York thing??
