One of the best scenes in Harry Potter!

Agreed

That arm dat swings back doe

When Emma and Tom were practicing this punch, Emma accidentally punched Tom for real.

Am I the only one that actually likes Draco Malfoy?

I wished she'd hit him harder!

You foul, loathsome, evil little cockroach !

and that's the moment he fell for her

truth be told, that's a lousy punch, looks like she poked his eyes

I liked it when Snape killed Dumbledore
