March is Magical Mischief month, which means that even you Muggles better solemnly swear that you’re up to no good.

The Wizarding World is holding a set of polls all month long to determine the ultimate moment of magical mischief from the Harry Potter films. Between Ron’s knack for Howlers, the ever-mischievous house elves, Harry’s magical (and sometimes not-so-accidental) Dursley mishaps, polyjuice potions gone wrong, and the endless pranks out of Weasleys’ Wizard Wheezes — this challenge might even be harder than the Triwizard Tournament. 

Magical Mischief voting will be done in rounds, including Muggle Mishaps (March 3); Ron’s Wrongdoings (March 5); Classroom Capers (March 9); and Disobedient Beasts (March 11). The winning moment from each round will go through to the next stage, which leads to a final deciding vote between the two most mischievous choices!

Fans can also find a Magical Mischief Art Challenge on Instagram for a chance to have their artwork featured. So channel your inner Fred and George and cast a vote (and maybe a spell or two) for your favorite mischief moments on the @HarryPotterFilm Twitter and Instagram pages, and the @HarryPotterMovie Facebook page. 

Mischief managed.
