Weasleys' Wizard Wheezes

Weasleys' Wizard Wheezes begins in Harry Potter and the Goblet of Fire as a product line without a shop: trick sweets and joke items invented by Fred and George Weasley, developed in their bedroom over a summer to their mother's loud disapproval and sold to schoolmates from homemade order forms. The twins are open about the dream behind it, a joke shop of their own, and treat their schooldays as research and development. Ton-Tongue Toffees and Canary Creams number among the early catalogue. By Harry Potter and the Half-Blood Prince the dream has an address: number ninety-three, Diagon Alley, a bright, crowded storefront that stands out on the whole street, stocked with the brothers' inventions and run by the founders in person.
