A psychopath getting 3 wishes from a genie would be a great horror movie.

I liked the one a while ago about making every blind person able to see again for exactly 6 hours before they go blind again

That sounded just viciously cruel

I'd just let them see, but make them temporarily go blind every time they'd be about to see something they care about, or are in a dangerous situation where being able to see would be useful.

- LMAO
Similarly, people who can’t walk can for a week. Just enough time to get moving again and may be get to a physio therapy session. Really get the hope in full swing

Reminds me of this classic:

Everyone already has Taste Buds in your asshole

https://www.foodbeast.com/news/science-says-testicles-and-anuses-have-taste-receptors/

I was cursed with this knowledge, and now you are too.
- Next time you're stuffing fistfuls of delicious bacon into your mouth, you might want to consider sticking a piece or two of crispy goodness into your crotch, then up your butt for good measure.
  
  That's a hell of a way to start an article.

  If you see taste receptors as chemosensors, then yes. We have those all over the place. In the lungs, brain, kidneys, the gastrointestinal system etc.. Even in sperm. Although a lot of those are not well studied yet, it has been found that - depending on the cells and region - they can serve specific purposes, like metabolic regulation, or airway relaxation. Basically a way for you body to react to chemical signals. However, afaik they do not contribute to the taste sensation when you're eating. (Except of those in your mouth, tongue and nose of course.) So you don't need to go all Cartman style.
  
  But(t), a lot of those findings have limited validity, e.g., because of investigations using cell cultures instead of in vivo studies, or because several animals have a different (or even completely lacking) set of those receptors than humans.

Homicide would be justified, I think. Or maybe just force-feeding him shit.
im laughing so hard the neighbours will think ive gone insane

I think people will figure something out when they begin to study the magical limb disappearing event and they find out you're the only person alive who was unaffected.

"I was born with an extra arm"
- Pics or it didn't happen
- Turns out it was the third leg
3rd wish: no one ever will figure out i was the reason for the limb disappearance
- People will have to rationalize your existence somehow. Being unable to ignore that you're the one person left on the planet with 4 limbs, everyone you meet now immediately labels you a freak and you find yourself ousted from society.
I am sure the mystery of disappearing limbs will FAR overtake the one person who wasn't affected. Worldwide panic and who knows what else. You could also wish 99% of people lose a random limb, and that would mean 70 million people would still have all their limbs.
It might not be obvious, depending on what counts as a "limb". Plus maybe OP already is missing one?

I mean, it'd still be a more accurate Death Note adaptation than what Netflix made, to be honest.

People who have to get a limb amputated and the right one gets randomly deleted: "Noice!"

Hopefully it's the correct limb for some of them.!
- Yeah, extra shitty for the ones who get a good limb deleted instead.

Wish 1: All humans are sterile.

Wish 2: All humans are immortal.

Wish 3: All humans are furries.

Now just sit back and enjoy the chaos.

I too play FFXIV
- Is that actually the plot for a FF game?

that's one way to get a leg up

The title and post kinda make me think of those 1-2 sentence horror stories.

"With tears in his eyes, the genie looks at me as he grants my third and final wish. There was nothing he could do to stop it."

Or imagine Death Note but it falls in the hands of Elon Musk.

There was a one shot sequel to Death Note where a dude got it, then decided it was more trouble then it was worth, and sold it via auction where the funds would be split up amongst all the accounts at his bank created before a certain date. The U.S. led by not-Trump won with a several trillion bid, and the dude got killed for breaking a new rule that immediately showed up in the book banning its sale.
