- Tara Lewis: "To remain indifferent to the challenges we face is indefensible. If the goal is noble, whether or not it is realized within our lifetime is largely irrelevant. What we must do, therefore, is to strive, and persevere, and never give up." — 14th Dalai Lama
- "Pariahville" is a term coined by a GQ article referring to Miracle Park, a community outside of Pahokee, Florida. It is extremely controversial for being founded as a home for registered sex offenders in response to registration laws that strictly limited where offenders are allowed to live. Since July 2013, over 100 sex offenders reside in the community, though a large majority of them are not pedophiles (who are barred from residency according to the website of Matthew 25 Ministries, a prison aftercare organization that founded Miracle Park).
- Sheriff Paul Desario was named after a friend of episode writer Erik Stiller.
