Muggleborns starting to sing songs in the Great Hall at random times.
Muggleborn, quietly: Is this the real life, is this just fantasy...
Another muggleborn, looking up from their plate: Caught in a landslide, no escape from reality
A lot of muggleborns: Open your eyes, look up to the skies and see...
One muggleborn: I'm just a poor boy, I need no sympathy
All muggleborns, softly: Because I'm easy come, easy go, little high, little low, anyway the wind blows, doesn't really matter to me...
Purebloods: What the...what?
All muggleborns, loudly: Mama, just killed a man, put a gun against his head, pulled my trigger now he's dead
Purebloods: What is a gun...?
(Okay I'm not continuing, though I would love to)
