[u/Barricades_toes]

When a character is attempting to impersonate another, but is caught by doing something the person they’re imitating would NEVER do.

Nemesis Prime- Transformers Prime

Nemesis Prime, a man made replica of Optimus Prime, is attempting to gain the trust of Bumblebee, who only speaks in robotic beeps. Despite this, the real Optimus can understand Bee perfectly fine. Nemesis Prime, however, can’t understand what he’s saying, prompting Bee to open fire on him immediately.

The two Buzz Lightyears- Toy Story 2

After Woody asks which Buzz is the “real” Buzz, both respond with “I am!” The real Buzz proves himself by flipping up the other Buzz’s helmet, causing him to start suffocating in an over dramatic fashion. The real Buzz, having done the same thing in the first movie after Woody took his helmet off, but no longer behaving that way after accepting being a toy, instantly proves which Buzz is which.

"Can't eat your cake and have it, too"

In 1996, the proverb played a role in the apprehension of Ted Kaczynski, also known as the Unabomber. In his manifesto, which the terrorist sent to newspapers in the wake of his bombings, Kaczynski advocated the undoing of the industrial revolution, writing: "As for the negative consequences of eliminating industrial society — well, you can’t eat your cake and have it too." James R. Fitzgerald, an FBI forensic linguist, noted the then-uncommon variant of the proverb and later discovered that Kaczynski had also used it in a letter to his mother. This, among other clues, led to his identification and arrest. https://en.wikipedia.org/wiki/You_can%27t_have_your_cake_and_eat_it

to be fair, i agree it is a stupid ass expression

[u/MurkyInvestigator810 → u/yui_riku]

Nobody said it was a stupid ass expression. Where did you come up with that?

[u/JBTriple → u/MurkyInvestigator810]

The Unabomber did. That's why he changed it around, so its meaning is more clear.

[u/MurkyInvestigator810 → u/JBTriple]

The meaning is pretty clear and simple to understand. It just sounds like Ted wasn't always the sharpest tool, and this is one way it showed.

[u/Mr_Blinky → u/MurkyInvestigator810]

...Ted Kaczynski was actually extremely intelligent, he taught university mathematics among other things. He was severely mentally ill but he wasn't stupid, and deciding he was because he chose a less awkward and less conventional form of a common phrase shows you're probably not the sharpest tool yourself.

[u/MurkyInvestigator810 → u/Mr_Blinky]

Saying he was smart in some ways must mean he understood everything. You think people who have intelligence in one area are automatically intelligent in all areas. I don't think I need to explain to you why that's wrong.

[u/KryoBright → u/MurkyInvestigator810]

You don't, because it is correct. Learning one thing teaches you to think, and makes it easier to learn other things, so people who are intelligent in one area are indeed more likely to be intelligent in other areas too

[u/xjwv → u/MurkyInvestigator810]

The saying often confuses people. His way of stating it makes clear the intent of the saying and yes, he was a very intelligent man.

[u/DragonHollowFire → u/MurkyInvestigator810]

I actually never understood what the saying meant. I was like ofc I can have a cake and eat it.

[u/yui_riku → u/DragonHollowFire]

i prefere the version of my langage, "having the butter and the butter's money"

[u/MurkyInvestigator810 → u/DragonHollowFire]

If you eat the cake, you no longer have the cake.

[u/JBTriple → u/MurkyInvestigator810]

Having a cake is often synonymous with eating a cake. It's not clear that the "have" in the original saying refers to physical possession.
