All about Harry Potter

You say, I say

You say you lost something, I say Nargles must be behind it.

You say stag, I scream "PRONGS, YOU'RE ALIVE!!"

You say finished, I say mischief managed.

You say Edward Cullen, I say Cedric Diggory.

You say turn on the lights, I say lumos.

You go to get the mail, I say there's no post on Sundays!

You say time machine, I say time turner.

You say hospital, I say St. Mungo's.

You say sadness and depression, I say it must be the dementors.

You say school, I say Hogwarts.

You say life, I say Harry Potter.
