Roy talks about having been in prison and advises the kids to lie, cheat, steal, and kill to get what they want. Of course their the innocent Brady's so they'll do no such thing.
Roy threatens the family with a gun and kidnaps Carol. Jan drives recklessly on the sidewalk. Mike punches Roy.
Greg and Marcia kiss. A lot of sexual innuendo (Alice says, "Sam promised to slip me a special tube steak," "Marcia's getting leied by those Hawaiian boys," and "We all want to be gay, don't we, gang?" etc.). Greg and Marcia watch each other change and struggle with attraction for one another.
Characters mention Aquanet and the Gap. The opening scene mimics the Indiana Jones movies.
Roy smokes a cigarette and eats an entire bag of psychedelic mushrooms. The next day he has a hangover.
