Over the phone, Norman Osborn refers to the person who gives him Menken's address as "Gargan." This is most likely the character Mac Gargan, a private investigator who will one day be the villain called The Scorpion.
Green Goblin: Although I will admit you have an annoying tendancy to... well, survive, the Green Goblin has every contingency in place to test the outer limits of that talent! (Uses his razorangs to cut Spider-Man's webbing) Until all that remains is a red and blue stain on the pavement!
Spider-Man: Hmm, now where have I heard that one before? (Creates a parachute out of webbing) Oh, yeah! From every super-villain I've ever come up against!
Green Goblin: Then perhaps it would be more original if I simply remained silent while watching you splat! (Throws a pumpkin bomb at the parachute)
Spider-Man: Well, it certainly would qualify as refreshing.
Green Goblin: Tonight, you're in a particulary unfriendly neighborhood, Spider-Man!
Green Goblin: Oh, what's wrong, Spider-Man? Off your game?
Spider-Man: Nah, game's good, Gobs. Just getting acquainted with the rules.
Green Goblin: Rule 1: Spidey must splat!
Spider-Man: Rule 2: Ignore rule 1. Rule 3: Make Gobby look goofy.
Flight Attendant: Sorry for the delay, Mr. Rowan.
Mr. Rowan: Don't apologize. I never do.
