'''The Film'''

* ''Zodiac'' is a terribly dark film, but there is one sequence that's laugh-out-loud funny.
-->'''Graysmith''': Doesn't it bother you that people call you Shorty?
-->'''Shorty''': Doesn't it bother you that people call you retard?
-->'''Graysmith''': Nobody calls me that.
-->'''Shorty''': Right.
** He then walks over to Avery at his desk in the next scene.
-->'''Graysmith''': Hey, does anyone ever call me names?
-->'''Paul Avery''': [[SuspiciouslySpecificDenial You mean like retard?]]
-->'''Graysmith''': Yeah.
-->'''Paul Avery''': [[BlatantLies No.]]
** The Aqua Velva scene.
* During the TerribleIntervieweesMontage:
-->'''Woman:''' Have you considered the killer might be Paul Avery?
-->'''Toschi:''' [[DeadpanSnarker Frequently]].
* Graysmith referring to his sons as "colleagues" when talking on the phone, and telling them not to tell Mom about their special project
