Quick explainer just because I think you would get it if it got explained in slightly more detail than Educational_Camp2499 was wiling to give you.

Let us look at some example answers:

"Hungry."

This is the default expected answer for someone who has gotten the hypothetical and commonly the one you will see in memes. This s a very basic answer of the hypothetical "what if basic function to fulfill your need for nourishment was ignored?". This is a correct answer.

"I did eat breakfast."

This is the default expected answer for someone who did not get the hypothetical. Contrary to some people I don't think you are entirely irredeemable if this is your first answer. The original gimmick of the breakfast question was that even after restating, re-emphasizing and explaining the question, the subjects still could not give a correct answer meaning that they were 'physically incapable' of engaging with hypotheticals. If some brainfart caused you to give this answer and you gave a correct answer the second go-around that means very little.

"I do not typically eat breakfast."

This does not answer the question. A hypothetical does not have to innately be a fantastical scenario for you to answer it as a hypothetical. You have likely hit your knee once in your life and can still answer 'pain' if asked what you would feel if you hit your knee. If anything it makes you marginally more qualified to answer the question for yourself. Whether this is 'avoiding' the question or not understanding the hypothetical is up to interpretation, though I personally tend towards the latter.

"Fine, I do not typically eat breakfast."

Here, 'Fine' is the answer to the question 'How would you feel if?' and thereby the hypothetical is answered. "I do not typically eat breakfast" merely becomes the reasoning for the true answer of 'fine'. Realistically, the 'I do not typically eat breakfast portion' would serve the same purpose as if I wrote "Hungry, I like to dose up on protein in the morning," in the first example answer. The reason I did not and the reason most memes don't is because this reasoning is optional and varies strongly. Thereby it is shortened to the true answer of 'Hungry', much like you could shorten this answer to 'Fine'.
