Usual disclaimer about Harry Potter copyright belonging to J.K. Rowling. It is not mine! And this is only a joke.
Rouge Dementors
Minister Fudge (to Barty Crouch, jr.): "... and now this Dementor will kiss you!"
Dementor. It seems to have heard. Suddenly it becomes nervous, passes slowly a finger to its lips, rummages in its cloak, for a long time ... finally! It pulls out a small object from a pocket and starts to put on lipstick. (Rouge lipstick).
It "looks" in a pocket mirror. It smiles. And, with a rose between its teeth, it advances dancing on tiptoe towards the increasingly horrified Barty Crouch...
Barty Crouch, jr.: "Noooooooooo !"
Dementor: *SSMMMUAAAAAAACK *
From nowhere begins a violin music and from the floor emerges a gaudy heart-shaped pink bed, while the Dementor is suddenly spouting French words..
Minister Fudge (horrified. Yes, he, too): "AAAAAAAAAAAAAAH! I did not know it was so horrible!"
Tale born from a recurrent misprint I saw on : "rouge dementors" ! But how could they be?
This is an answer.
But very worse things I have seen in an episode of "Doctor Who": Whisper Men... sssshhhh...
