The title, "Thinman" is a parody of the fictitious monster, Slenderman.
Dean, talking of the internet's lack of veracity, mentions a shark attacking a helicopter. In 2001, a photoshopped hoax e-mail went viral; it showed a great white in midair attacking a man suspended from a USAF Pave Hawk helicopter with the Golden Gate Bridge in the background; its caption claimed that National Geographic magazine voted it the photo of the year. This e-mail is so famously false it is used in textbooks as an example of the power of hoaxes.
This is the second time Nicholas Carelle (Deputy Tom Norwood) has guest starred on the show. The first time was Season 6 Episode 14 "Mannequin 3: The Reckoning", where he played Janitor Steve.
Dean says "sounds like sad times at Bitchmont High." This is a reference to a well known teen comedy from 1982 called Fast Times at Ridgemont High.
Dean asks, "What about the rest of the Bad News Bears?" He is referring to the 1976 comedy, "The Bad News Bears," about a Little League baseball team made up of the league's worst players.
