Kingpin: I have been waiting for this moment for some time.
Spider-Man: What do you have in mind, a pie-eating contest?
This is one of the few episodes where Spider-Man throws a punch.
This episode was released on video and DVD called "Return of the Green Goblin" along with other episodes.
First appearance of The Spot in an animated cartoon.
In the comics, Jonathan Ohn didn't fall into the portal, he stepped into it causing him to come out white with spots on him (like this episode). Spider-Man and the Black Cat fought him once with Spider-Man laughing at his name. The Spot had been defeated for a while, but later returned as a member of the Legion of Losers. Other villians with him were Grizzly, The Gibbon, and Kangaroo II.
This episode clearly aired out of order. The number is right in the title, you think it'd be a hard thing to mess up!
