Want to make a wish? Just ask the Monkey’s Paw! No strings attached.*
Just create a post that starts with “I wish ___”. Other users will then grant you the wish, and probably not how you intended.

Granted. All humans were blind to undefinable-xxx. They now have the third eye seeing with clarity. The visions of cthulu quickly drive all of humanity to extinction.
Every person healed "takes" their sense from someone who had it. ie - A blind man can now see, but the sighted person next to them is now blind.
The blind sees the other world, the deaf hear it's inhabitants and the mute talk their language. A New cult is born.
It works for all those who are disabled now, but not for any who become disabled in the future. Society lets any progress we've made in accessibility lapse, and the next generation has to fight the last century of battles that the community has won all over again. No ramps, no textured or audible crosswalks, no fluent braille users to learn from, and even less patience and understanding from everyone else.
