How much of the life of Harry Potter has entered into our society?

Do you find yourself saying "Sorry 'bout thaat" like Hagrid.
Or "Right then, Griffindor" like the sorting hat.
Do your kids have teachers with nicknames of "Mad Eyed Moody" or "Madam Hooch"?
And a caretaker named "Filch"?

Or are we the only family that loves Harry Potter?
