Weasleys' Wizard Wheezes is a popular joke shop that started as a small school business created by Fred and George Weasley in the fourth book. It opened its doors at Number 93 Diagon Alley in the summer of the sixth book, using Harry Potter's Triwizard Tournament Winnings as starting capital. Weasleys' Wizard Wheezes sells joke and trick items, useful novelties, sweets, and Defence Against the Dark Arts items. The front of the shop is described as a fireworks display against the muffled backdrop of dull shops. Some of their products are U-No-Poo, Skiving Snackboxes, trick wands, spell-checking and Smart Answer Quills, reusable Hangmans, Daydream Charms, muggle magic tricks, Edible Dark Marks, Shield Products, Peruvian Instant Darkness Powder, Decoy Detonators, joke cauldrons, Wonderwitch beauty products and 10-second pimple vanishers, Pygmy Puffs, love potions, and more.
