"Self-indulgence is, like, when you're talking about stuff you like to talk about without being entertaining at the same time. I don't mind being self-indulgent as long as we're making them laugh and think at the same time." --- Kevin Smith, in his Premiere interview with Ben Affleck.

Jersey Girl, anyone?
