There's a great quote I've long associated with Willow Rosenberg in Buffy the Vampire Slayer that deals with the idea of not being a true, self-respecting Witch without her familiar.
If memory serves correctly, because I no longer have the quote, it was something about a proper Witch's familiar being a frog. At the time, the quote struck me as amusing because I owned a Pacman Frog, so I incorporated it into a signature file for an old yahoo email address I was using at the time.
The quote became a source of amusement for Mama Bear and me, and eventually it just faded into cobwebbed memory. But it also has made me really think about the role of familiars in my spiritual practices.
