{{Muggles' Guide to Harry Potter/Beginner Spoiler}}
GeorgeFred and FredGeorge have been interested in practical jokes all during all their [[Muggles' Guide to Harry Potter/Places/Hogwarts School of Witchcraft and Wizardry|Hogwarts]] years. Zonko's Joke Shop was their favorite store in [[Muggles' Guide to Harry Potter/Places/Hogsmeade|Hogsmeade]]. Beginning in [[Muggles' Guide to Harry Potter/Books/Goblet of Fire|''Harry Potter and the Goblet of Fire'']], we see them turning their (often underestimated) talents to inventing and developing unique wizarding jokes and novelties. They begin a small mail order business, which we hear about when their [[Muggles' Guide to Harry Potter/Characters/Molly Weasley|mother]] discovers the order forms and expresses her disapproval. Their dream of starting their own joke store is realized when [[Muggles' Guide to Harry Potter/Characters/Harry Potter|Harry]] gives them the 1000 Galleon [[Muggles' Guide to Harry Potter/Major Events/Triwizard Tournament|Triwizard]] prize he won. Harry says that given [[Muggles' Guide to Harry Potter/Characters/Lord Voldemort|Voldemort's]] return, "We could all do with a few laughs."
In [[Muggles' Guide to Harry Potter/Books/Order of the Phoenix|''Harry Potter and the Order of the Phoenix'']], the twins actively test and market their products at Hogwarts, often using first year students as paid guinea pigs. Somewhere during the year, they secure the store premises in Diagon Alley and, shortly after [[Muggles' Guide to Harry Potter/Characters/Albus Dumbledore|Professor Dumbledore]]'s departure, leave school early to operate full-time out of those premises.
