U-No-Poo

"WHY ARE YOU WORRYING ABOUT YOU-KNOW-WHO? YOU SHOULD BE WORRYING ABOUT U-NO-POO THE CONSTIPATION SENSATION THAT'S GRIPPING THE NATION!"

- Advertisement poster in the window of Weasleys' Wizard Wheezes

U-No-Poo is a product of Weasleys' Wizard Wheezes that causes constipation in the unknowing taker. The product was advertised in the main window of the shop in the summer of 1996 in yellow writing and on a purple background. Mrs Weasley was less than impressed with the slogan, fearing that her sons would be "murdered in their beds" for using the moniker of the Dark Lord.
