A few minutes ago, whilst reading the part when Professor Lupin uses 'waddiwasi' to shoot gum up Peeves' left nostril in the chapter: The Boggart in the Wardrobe; I realised how funny the HP movies would be if they added scenes with Peeves in them. Like if they added the Deathday Party in book (movie) 2 when Peeves throws peanuts at Myrtle and calls after her : 'Pimply! Pimply!'
