Nathan's voiceover at the beginning and end of the episode is taken from Shakespeare's play "The Tempest".
Nathan: (voiceover) People say hell is endless. They say it's our worst nightmare. The face of our darkness. But whatever it is, however it is, I say hell is empty, and all the devils are here.
Chris: (to Haley) Look, just because I tell the truth, and just because I say you smell good when you do, and you do, does not mean I'm here to cause trouble. Okay? I really am here to help.
Haley: If that's true... then you can stay. But you are on double secret probation. Don't screw up!
Chris: Nice! Haley, let me ask you something, um, what's the deal with Alex and her boyfriend?
Haley: I'll see you later.
Haley: Haley! Chris Keller missed you.
Haley: (as Brooke's dad walks in) Wow, it's like seeing a big foot.
Victoria: Trust me, his feet aren't that big.
Haley: (referring to Chris as she walks out) Stupid, lying, arrogant, third-person talking jerk!
Haley: (frustrated) Harry Johnson.
Chase: (to Chris Keller) Stop telling my girlfriend that her song's crappy, you hear me?! I had an amazing sex life until you showed up, you...peacock-looking dork!
