The Wandelgek had been browsing through the eye popping pages of Weasley’s Wizard Wheezes catalog for a while, which made him plunder his vault at Gringotts Wizarding Bank, thus being well prepared for another shopping spree, before entering the famous fun shop…

Entering through the door, a bell started rinkling and The Wandelgek arrived in a shop that was a multi storey explosion of colors and a true feast for the eye.

Shelves were stuffed full of Peruvian instant darkness powder, magical love potions, puking pastilles and….

…oh boy!… a box full of real decoy detonators?

His hands full with loads of fun stuff, he arrived at the counter and paid a small fortune. As The Wandelgek approached the door to leave the shop, he was aproached by George Weasly. I’ve got some change for ya. You paid too much. Ah no change needed replied The Wandelgek. Grateful, George put the sickles and knuts in his pockets and then grabbed in his right breast pocket. A piece of parchment appeared. He unfolded it and he added: “just say the words: I solemnly swear that I’m up to no good” and afterwards the words: “Misscief managed!”, then he just put it on top of everything else The Wandelgek was already carrying.

“Thanks” said The Wandelgek not understanding what he needed a piece of empty parchment for, but he didn’t want to seem ungrateful either. Then he left the shop.
