The Whole show, in some way or another, revolves around names of ghosts or spirits. (The high school is called "Casper High" referring to Casper the friendly ghost.) Also, the town they live in is called Amity Park referring to the Amityville where ghosts/spirits caused a man to kill his family. Also, Danny's high school mascot is a raven, referring to Edgar Allan Poe's famous poem, 'The Raven'.
Lancer, an English teacher, uses book titles as exclamations instead of cursing.
In the original version, Danny and his friend Samantha were supposed to have a telepathic connection.
Sam and Tucker would be in all but one episode of Danny Phantom.
