Comic Relief (in-universe)

"Comic Relief uses laughter to fight poverty, injustice, and disaster. Widespread amusement is converted into large quantities of money."

- Albus Dumbledore explaining this organisation to wizard readers.

Comic Relief is a British charitable organisation devoted to helping the needy, mainly through fundraising via a biennial telethon. Sometime before his death in 1997, Albus Dumbledore made arrangements via this organisation to have versions of Fantastic Beasts and Where to Find Them and Quidditch Through the Ages published for Muggle readers, with the intention that proceeds from the sales of these books would go towards a fund set up in Harry Potter's name by this organisation and J.K. Rowling.

They are not be to confused with Comic Relief USA.
