Ok, this is a thing where you put a verse of a well known song, but change the lyrics to a harry potter theme!
I will start:
(Set Fire To The Rain- Adele)
I Set Fire To The Snape!
Watched Him Scream As I Torched His Cape!
Watched Him Shout As I Laughed
And I Heard Him Call Dumbledore's Name, His Name
From The Philosophers Stone!
