Fred looked down around at everyone's smiling faces. 'If anyone fancies buying a Portable Swamp, as demonstrated upstairs, come to number ninety-three, Diagon Alley – Weasleys' Wizarding Wheezes, our new premises!'

Everyone cheered as George began, 'Special discounts to Hogwarts students who swear they're going to use our products to get rid of this old bat,' and with that he pointed to Umbridge.

'STOP THEM!' came an unusually high shriek from the Defence professor, but as the Inquisitorial Squad charged towards the two twins, they shot up in the air and with one last look down at their adoring crowd, Fred saw one certain poltergeist across the room.

'Give her hell from us, Peeves.' Peeves saluted and Fred and George kicked flew off into the sunset, following amazing applause from the students below.
