The Witcher Easter eggs

A virtual Easter egg is an intentional hidden message or feature in an object such as a movie, book, CD, DVD, computer program, or video game. The term draws a parallel with the custom of the Easter egg hunt observed in many western nations.

This practice is analogous to hidden signature motifs such as Diego Rivera including himself in his murals or Alfred Hitchcock's legendary cameo appearances.

This article will catalog easter eggs in The Witcher. The developers have stated that there are a fair number of them.

Please note that some of these are unconfirmed, since I personally do not have the background and knowledge to know all of the references possible here. If any reference seems bogus, please discuss it on the talk page or put a note beside it.

Visual Easter Eggs

 * The Vizima Temple Quarter at night loading screen has a McDonald's sign on the door approximately in the middle of the image.
 * The runes on a sword tempered with temporary runes spell silentrun with what seems to be the futhark-based runic alphabet from Ultima.

Auditory Easter Eggs

 * If you listen closely to the music during the cut scene in Act II where the boat is moving away from the docks (from Vizima to the Swamp) and the camera focus moves to the surface of the water, you can hear a musical cue similar to the Jaws theme.
 * Some random roaming NPCs will sometimes whistle The Imperial March from Star Wars Episode V: The Empire Strikes Back.

References to Other Games/Media

 * The detective (named Raymond Marlowe) might seem strangely familiar if you've read any of the "Philip Marlowe" novels by Raymond Chandler.
 * H. P. Lovecraft references:
 * Certain things going on in the swamp are a clear nod to the novels and short-stories of H. P. Lovecraft.
 * The first sentence of the description of Dagon is taken from H. P. Lovecraft.
 * The person who invented explosives in The Witcher is called Alfred Nabel, and it is stated in the Prologue that he did not intend his invention to be used to blow things up. This is a reference to Alfred Nobel, who invented dynamite and later on deeply regretted his inventing of the explosive due to its use on the battlefield as a means of killing. This led him to use the great fortune dynamite brought him to fund the Nobel Prize.
 * Monty Python references:
 * There is a discussion beetween lumberjacks about wild flowers and crossdressing.
 * Poor people in the Vizima Temple Quarter slums will sometimes say "Society made me what I am" as Geralt passes by.
