In the film's pivotal final scene, Woods cross-examines the decedent's daughter, Chutney. Her alibi is that she was in the shower while her father was killed. Chutney admitted to getting a perm earlier in the day, to which Woods delivers the iconic line, "The first cardinal rule of perm maintenance is that you are forbidden to wet your hair for at least 24 hours after getting a perm at the risk of deactivating the ammonium thioglycolate." Mic (and great advice) dropped.
