You found a bottle that cointained a genie who only can grant wishes related to fat. And you rub it to see if something happens.

Then, a purple cloud appears, and the genie appears.

"Finally... After so long..."

He glances at you.

"So you set me free. Thanks. I'm a genie. You have three wishes blah, blah, blah. Though you can only wish something related to fat. So what do you want to wish?"
