Let's face it. Minerva McGonagall is never retiring, and no one in their right mind would take on the Defence Against the Arts position ... so you had to settle for teaching Muggles. But why not let the entire world know that Hogwarts was your first choice and pick up this sticker from Etsy Canada?
This particular sticker says "Hogwarts wasn't hiring, so I teach Muggles instead," accompanied by the castle, a broom and the Sorting Hat. Each handmade sticker measures 76 mm x 55 mm, and you can stick it to your laptop, a coffee mug, a phone case or just about anything else. But the best part? It's only $4.50 shipped!
They usually come in a few different colours (including colour stickers and ones with a white background), but those are sold out – so all that's left is the black text with a clear background. And since a couple dozen people have them in their carts, you should probably act fast before they all sell out entirely!
