According to actual myth it'd be something like -
Wisher - "I want to be a woman."
Djinn - "You sure? That's your third wish."
Wisher - "I'm the richest person who ever lived and am immortal. Make it so!"
Djinn - "Ok. . ." *Finger snap* "You're now a woman and I'm out of here!" *Djinn vanishes.*
Wisher - "HEY! NOTHING HAPPENED! GET BACK HERE LIAR! Oh well at least I'm rich and immortal!"
*One year later.*
Wisher - "Why am I always having to pay 99% of taxes and have all these illnesses that won't got away! Worst of all is that I get these horrible cramps and pee nothing but gunk and blood once a month!"
