Everyone's favorite wisecracking neighborhood web-head was originally just a fly on the wall.

After hitting it big with his creation of the Fantastic Four in 1961, Stan Lee spent the next year racking his brain for the next big thing. And then a fly flew in.

After seeing the winged insect crawl up a wall at Marvel's offices, the comics legend immediately thought what the company needed at that very moment was a guy who could stick to vertical surfaces.

So he came up with the next amazing superhero: Stick-to-Wall Man.

Even though a name like that is pure gold, Lee tried out a few others like Insect-Man, Fly-Man, and Mosquito-Man until he finally hit the bug on the head with the most dramatic of all, Spider-Man.

He then enlisted artist Steve Ditko to whip up the costume design and presented the awesome idea for an awkward teenage hero with all the powers of a spider to Marvel head Martin Goodman.

He as expected replied, “That's the worst idea I've ever heard.”

And the rest, as they say, is history.
