Every year, the Weasley/Potter clan go to The Burrow on the date of the battle of Hogwarts, and watch a Disney film. Most of the afternoon is spent arguing on what film to watch, and it always ends up with Molly I having to do a vote.
Eventually, they all settle down and watch the film, but it takes the rest of the evening to finish it as they have been arguing all day.
They originally did the arguing to take George's mind from Fred and therefore depression. Now, though, they just do it for fun and games.
