Corrupt a Wish

I grant your wish of making your desk 3" lower. You may now lower your chair and have your feet rest on the ground. Why on earth you would wish that, I can not imagine as the ground is made of lava. Perhaps you work better when your feet are being burnt off.

I wish that I could have a genie that is capable of granting me any wish I want, the way I want it. I want a genie that simply gives me what I desire with no strings attached. That genie must not have a malevolent mind nor any desire to corrupt my wish.
