Who said dead Jim?

The phrase "Dead Jim" is most famously associated with the character Montgomery Scott (Scotty), the chief engineer of the starship Enterprise, in the original Star Trek series.

While he never actually said the phrase exactly, the character used similar expressions like:

* "Jim, you're dead!"

* "He's dead, Jim!"

This phrase, along with the rest of the series, has entered popular culture and become a meme, often used humorously to express surprise, disappointment, or even excitement.
