You know you're a potterhead...

You know you're a Potterhead when, while you're working on your son's Harry Potter Halloween costume, he points his wand at you and yells, "Stupify," but before he can finish, you point your butter knife (which you're using to try to pry the monster eyeballs out of gag glasses so that he can use them for Harry's glasses) and yell, "Protego," before he can finish.

And he freezes.
