Most hashtags on Twitter can be disregarded. Most trends and memes can be ignored.
But some do work and one that started late on Thursday night, #TweetAPictureYoullNeverDelete, was an absolute treat.
Despite it not being a football-specific tag, an impressive number of the pictures were focused on the beautiful game.
We've capped our list at 15—it could easily have been more. Enjoy!
Andrei Arshavin, you tease. One of the big pluses of the hashtag was not merely reliving classic pictures but discovering new ones. For us at least, this Arshavin photoshoot was in the latter category.
Worst. Meme. Ever.
It's wrong, for one thing. It's misspelt all over the place for another. And Higuain ended up at Napoli, not Arsenal.
This makes the top of our list because it's precisely the sort of thing that is ridiculous to keep hold of and yet now we've seen it, we also can't imagine deleting it.
