I love the deleted scene where the Goldsteins sisters sing the Ilvermorny School song. It's brilliant, catchy and you can just see the two of them as young girls being so proud of their school as they sing it.

I really want to see the favour returned in a post-movie fic where the two Scamander brothers are stateside and someone asks if Hogwarts has a school song. The Americans are expecting something grand and boring (probably in latin or something) because Hogwarts has been around for a thousand years. Instead, the two brothers start singing 'Hoggy Warty Hogwarts'. By the time they get to 'dead flies and bits of fluff' the brothers are really getting into it and all the bystanders are horrified.

+ If there's other British wizards and witches there too, including really grim Ministry officials who are singing along
++ If Graves, having fought alongside British wizards in the war, knew what was coming and was preemptively embarrassed
