How happy is the blameless vestal's lot?

Mary: The quote goes:
''How happy is the blameless vestal's lot? 'The world forgetting, by the world forgot. Eternal sunshine of the spotless mind. Each prayer accepted and each wish resigned.''
Clem: I want to be a great big, huge elephant... with a huge trunk like that.
Joel: Clem? Clementine?
