Yeah, I remember reading that BRAVE & THE BOLD 115 story when I was about 11 years old.


Even at that age, it seemed implausible to me, Atom running around Batman's brain, pressing on different motor-centers of the brain to make him move, like a giant comatose marionette.
But it was a fun story, and I took it in stride.




Did you read the story in BATMAN 260, with the Joker?

(February 1975, story by Dennis O'Neil, art by Irv Novick and Dick Giordano)

The Joker sprays a gas that causes Batman to laugh uncontrollably in odd situations, such as viewing a corpse at a funeral.
Which causes Batman to double over with laughter each time, unable to fight, when the Joker tells Batman sick, morose, or just plain stupid and unfunny jokes.

A doctor injects Batman at the end of the story with a cure to Joker's poison, and asks Batman:

DOCTOR:"How were you able to overcome the serum last night and save my life?"
BATMAN: "Simple Doctor. I reasoned that the drug caused me to laugh when I was confronted by horror... death... violence !
Therefore, I theorized that something genuinely funny would affect me the opposite way.
So
[while fighting the Joker ] I simply concentrated on the funniest scenes from all the Marx Brothers pictures."

You can almost hear Batman saying this in an Adam West voice.
