Or a hammer. I was going to say "the only time this guy ever used a hammer was putting nails in his drywall to hang a poster", but then I remembered there's a company that makes metal posters with just about every nerd IP like funkopops, and one of their selling points is you just glue a magnet to your wall and slap the metal poster on it.
I've seen those too. The idea is so you can replace them easily, so you can throw your pointless distractions away to the landfill just as passively and arbitrarily as they entered into your life. You have to be able to do it quickly so excreting the old product doesn't get in the way of ingesting the new.
