Slytherin vs. Gryffindor Quidditch Team.
Gryffindor won

"But you love that family, don't you, Potter?" Malfoy mocked. "Do you spend your holidays with them? How you even stand that stench, I don't understand. Although, having lived with Muggles, you'd probably be happy with a rubbish dump?"

Harry clung to George. Angelina, Alicia, and Katie held Fred back as he lunged at Malfoy, who laughed in their faces. Harry looked around for Madam Hooch, but she was still scolding Crabbe for the unfair Bludger attack.

“Or maybe you remember how your mother’s house stank,” Malfoy continued, backing away, “and you recognize a familiar smell in the Weasley pigsty?”

Harry didn't notice he'd let go of George; a second later, they were both racing toward Malfoy. He'd completely forgotten that this was happening in front of all the teachers; he'd only wanted to hurt Malfoy as much as possible. There was no time to draw his wand; with the fist clutching the Snitch, he struck his enemy in the stomach with all his might.

— Harry! HARRY! GEORGE! STOP!

He heard the girls' screams, Malfoy's yell, the referee's shrill whistle, the roar of the stands, but he didn't care. Until someone nearby shouted, "Impedimenta!" and he was thrown back by the force of the curse, he pounded Malfoy with his fists.

"What are you doing!" Madame Hooch shouted.

Harry rose to his feet. Madam Hooch must have knocked him out with a curse. Malfoy was crumpled on the ground, moaning and whimpering, his nose bleeding. George's lip was swollen; Fred was being held down by three Chasers, and Crabbe was giggling behind him.
