* [[BigLippedAlligatorMoment Big-Lipped Orangutan Moment]]: Duke's flashbacks.

* CrossesTheLineTwice: Duke's plans for Lucy. He was joking, as what he said was mainly to alert Gonzo to just how much trouble that they could get into if they didn't lose her, and fast. It starts out horrible, suggesting that they feed her acid and let cops pay money to gang rape her. Right about the time he gets to the part about hanging pictures of Jesus all over the room while this is happening, it becomes clear that he's not seriously suggesting any of it.

* FilkSong: [[AvengedSevenfold "He who makes a beast out of himself, gets rid of the paaaaiin of beeeeiiing a maaaannn... YEEEEEEAAAAAAAHHHH!!!!!]]

--> '''Duke''': All right, listen. In a few hours, she'll probably be sane enough to work herself into a towering Jesus-based rage at the hazy recollection of being seduced by some kind of cruel Samoan who fed her liquor and LSD, dragged her to a Vegas hotel room and then savagely penetrated every orifice in her body with his throbbing, uncircumcised member.

* TrueArtSticksItToTheMan: Once you get past all the drug-fueled insanity, the book is essentially a screed against the Nixon era.

** the laundry list of drugs in the trunk of the car: "two bags of grass, seventy-five pellets of mescaline, five sheets of high-powered blotter acid, a salt shaker half-full of cocaine, and a whole galaxy of multicolored uppers, downers, screamers, laughers..."
