On the day Grindelwald is to be given the dementor's kiss, Graves shows up at Azkaban with a confetti cannon, a bottle of champagne, and a boombox blaring Green Day's "Ha Ha You're Dead".

For inspiration:
"Ha Ha you're dead
The joke is over
You were an asshole
And now you're gone
As your ship is going down
I'll stand by and watch you drown

Ha Ha you're dead
You're gonna be dead"
