Origin
On an episode of the 1967 Spider-Man TV series called “To Cage a Spider”, Spider-Man is tracking down two thieves who had robbed a bank. They escape in their car, as one of them throws a vibrator at Spider-Man as he tries to swing down and catch them. Unfortunately for him, he gets hit by it, and plummets to the ground. A mob quickly crowds around him while unconscious. One of the spectators there, Captain Stacy, takes him to a hospital to heal. Part of this scene shows a moment where Spider-Man regains consciousness and is holding his chest in pain and confusion.
(Look around 7:14-7:15.)
