"I can't fiddle with a mind until it's been wiped clean. The human mind is like Van Halen. If you just pull out one piece and keep replacing it, it just degenerates." -- Topher Brink (played by Fran Kranz), on the Fox television program, Dollhouse, in the episode "Instinct" (created by Joss Whedon, episode written by Michele Fazekas and Tara Butters, first broadcast 2009-10-02)
