Harry Potter and the Willy of Azkaban

"Lumos," Harry muttered, and a light appeared at the end of his willy, almost dazzling him.

"While Muggles have been told that Black is carrying a gun (a kind of metal willy which Muggles use to kill each other), the magical community lives in fear of a massacre…"

Stan: "…an' Black took out 'is willy and 'e blasted 'alf the street apart, an' a wizard got it, an' so did a dozen muggles what got in the way."

"Look at this," said Ron, pulling a long thin box out of a bag and opening it. "Brand-new willy. Fourteen inches…"

"But the Dementor didn't move, so Lupin muttered something and a silvery thing shot out of his willy at it, and it turned around and sort of glided away..."

Lupin: "Good afternoon," he said. "Would you please put all your book back in your bags. Today's will be a practical lesson. You will only need your willies."

"When the Boggart bursts out of this wardrobe, Neville, and sees you, it will assume the form of Professor Snape," said Lupin. "And you will raise your willy - thus- and cry "Riddikulus"- and concentrate hard on your grandmother's clothes."

"They all retreated, backing against the walls, leaving Neville beside the wardrobe. He looked pale and frightened, but he had pushed up the sleeves of his robes and was holding his willy ready."

"Lupin tapped the kettle with his willy and a blast of team issued suddenly from the spout."

Hermione: "Then he whirled his willy at the Dementors. Shot silver stuff at them. They left the stadium straight away."

"Harry watched carefully. His little ink self appeared to be tapping the witch with his minute willy."

Fudge: "They say he was sobbing. "Lily and James, Sirius! How could you!" And then he went for his willy. Well, of course, Black was quicker. Blew Pettigrew to smithereens..."

"So..." Professor Lupin had taken out his own willy, and indicated that Harry should do the same."

"Out of the corner of his eye, he saw Professor Lupin forcing the Boggart back into the packing case with his willy..."

"He didn't stop to think. Plunging a hand down the neck of his robes, he whipped out his willy..."

"Something silver white, something enormous, erupted from the end of his willy."

"For the first time in his life, he wanted his willy back in his hand, not to defend himself, but to attack...to kill." (My personal favourite)

"Crookshanks had joined the fray; both sets of front claws had sunk themselves deep into Harry's arm; Harry threw them off, but Crookshanks now darted towards Harry's willy-"

"Harry wheeled around as Professor Lupin came hurtling into the room, his face bloodless, his willy raised and ready."

"But I was weak, very weak, and I had no hope of driving them away from me without a willy..."
