Its a quirk in binary math with 8 digits. If you "roll the odometer" past 0, it resets to 255

 0000 0011 (3)
-0000 0001 (1)
=0000 0010 (2)

 0000 0000 (0)
-0000 0001 (1)
=1111 1111 (255)

I think you missed the joke

Genie grants the wish, and then deducts one from the pool of remaining wishes.

Edit 1: And it is implied that the Genie stored the number of remaining wishes as an eight bit unsigned integer, where subtracting one from zero gives 255.

It is worth noting that unsigned integer subtract-from-zero exploits were common in video games from around the time that Disney's Aladdin was released.

Edit 2: No discussion of amusing subtract-from-zero bugs is complete without a link to Nuclear Gandhi. (Even though it is now believed not to have been a subtract-from-zero bug.)

He is saying factorial of zero, so more a math nerd than a computer nerd.

Yes. I caught the factorial reference, but wanted to address the question, in case it was also in earnest.

Missingno appears.

I don't see how the vacuously true statement 0 != 1 has any relevance here.

First, "make it 0!" - * Number *! As a "surprise factorial" (as seen in comments in this very thread making this exact joke) is a common joke in threads like this and that was the only connection I could make for this meme, having no previously knowledge of binary quirks.

Second, I don't know if you were trying to be a dick or you're just some overly wordy ass clown high on your own farts, but how on earth is me explaining what I thought a joke meant, showing why it didn't work, and then asking for help to understand it vacuous?

I assumed that you understood that the original joke was about having 0 wishes.

I also assumed that you were making a joke about factorials.

I decided to make my own joke about "!=" in your joke being misinterpreted as the programming symbol for "not equal".

My statement should be read as "0 is not equal to 1". This is a vacuously true statement, as it does not rely rely on any input, and is always true.

Shouldn't it be -1, not 0?

Depends. If the wish counter decrements after fulfilling the wish, then it works.

• Wish 1: Wish for the numeric rule to operate in 64-bit unsigned integer space.

• Wish 2: wish for 0 wishes.

• Wish 3: Wish for minus 1 Wish.

Result: now be left with 1.8446744073709551616*10^19 Wishes.

Avarage argument in any science related space:

This is why math nerds prefer to talk in a dull tone. The least bit of excitement, and your equation is suddenly wrong.

"Eh, good enough, ticket closed"

Not only is 0 != 1, but also 0! = 1.

sadly I don't know which one you mean

I always thought he was a "fake prince" because he was the prince of a country that didn't exist. Like, sure, you're the prince of this nonexistent country, see how far that gets you I guess. Otherwise Genie would either have to make new land out of nowhere somehow, or displace people who already lived/ruled in a location, which seems somewhat against the rules.

I'd kick your ass if I didn't spend all three of my wishes on churros from 7-11.

If it was impossible he shouldn't have accepted the wish. Aladdin already gets a wish rejected for not being possible. Fulfilling a wish with something different than what was wished for shouldn't be a thing.

And what does being a prince of a non-existent country even mean? That's still not a prince in any capacity (as confirmed by the story). It's just a scam.

Plus an easy way to accomplish this is just to make Aladdin the lost son of someone. It's a pretty common trope for royal kids to end up missing and raised as commoners, especially in Disney stories.
