Supernatural Season 8 Episode 20

Charlie: So, you gonna invite me into your dungeon, or do I got to answer your questions three first?
Referencing the 1975 movie Monty Python and the Holy Grail. To cross the Bridge of Death and pass Gorge of Eternal Peril, the bridge-keeper demands that each supplicant must answer three questions. The questions range from simple to inane to incredibly complicated, and if the supplicant fails than they are catapulted into the Gorge.

Dean: Uh, Special Agent Hicks. This is my partner, Special Agent Ripley.
Referencing the movie Aliens (1986). Two of the main characters are Corporal Dwayne Hicks (Michael Biehn) and Ellen Ripley (Sigourney Weaver), and they are two of the four survivors at the end of the movie.

Dean: We'll come back later when Doris Do-Right isn't here anymore.
Referencing Dudley Do-Right, the dim-witted but heroic Canadian Mountie immortalized in The Rocky and Bullwinkle Show (1959-1964), and later spun off into his own show and a live-action movie. Dudley fights against Snidely Whiplash with the assistance of Horse, his horse.

Dean: Yeah, whatever you say, Wargames.
Referencing the 1983 movie WarGames, which features a teenage hacker who inadvertently accesses a U.S. military supercomputer with AI programming. The hacker believes the computer contains game programs and unwittingly engages a Global Thermonuclear War scenario which the computer treats as real.

Dean: Does this mean we need to take Silkwood showers now, or is this still a case?
Referencing the 1983 movie based on the life of Karen Silkwood, who died while investigating report of wrongdoing at a nuclear plant. A scene in the movie features being scrubbed down in an anti-contamination shower for suspected exposure to nuclear materials. The term "Silkwood shower" has since entered usage as any long drawn-out shower designed to remove accumulated filth and contamination.

Dean: Who the hell is she--Jason Bourne?
Referencing the spy first created by Robert Ludlum in the novel The Bourne Identity (1980). The character went on to appear in eight subsequent novels, and was adapted into a TV movie in 1988 starring Richard Chamberlain. The novels were then loosely adapted into a series of movies, starting with The Bourne Identity in 2002.

Charlie: Wilhelm scream.
Referencing a c sound effect of a man screaming, initially attributed to the 1951 movie Distant Drums (titled "man getting bit by alligator") and performed by actor Sheb Wooley. It was used for the first time as a stock sound effect in the Warner Brothers film library in the 1953 movie The Charge at Feather River, and is named in honor of the character of Private Wilhelm, who it is associated with there. Since then it has become a running joke for sound engineers to incorporate it into movies, including Star Wars and the Indiana Jones and Lord of the Rings movies.

Charlie: Come with me if you want to live.
Referencing James Cameron's Terminator franchise. The line has been spoken, by various characters, in all three movies, as well as The Sarah Connor Chronicles TV series.

Charlie: She'd read me The Hobbit.
Referencing the 1937 novel written by J R R Tolkien. The novel is an "introduction" into Tolkien's Middle Earth setting, and a prelude to his subsequent Lord of the Rings trilogy. Hobbits are on average 3-1/2' tall creatures who live on average to the age of 100 and are known for their furry feet. It has served as the basis for both an animated movie in 2007 and a live-action film in 2012.

Dean: Always wanted to get Troned.
Referencing the 1982 movie Tron, which involevs a video gamer and computer programmer who is digitized and sucked into a virtual reality world where he discovers that each program is an individual, and they are rebelling against the Master Control Program.
