Locally, there's been a prank going 'round for a few years called 'dinking'
It's where you put an Engelbert Humperdinck LP at the head of every bin, pile, shelf of LP's in the store.
Then take a photo of it and post to social media.
There's enough to do the job in even the most well supplied LP sections.
It's a real turn-off, makes me loose interest in browsing the shelves.
