yea. I am not sure where this comes from.. maybe the joke-y Aladdin genie? or other more malevolent genies from other stories? honestly I don't remember, but I can imagine a genie being very accomodating, or very evil, in the way it will grant the wish.
Thank you for sharing! I also remember a blue and black genie - where one was malevolent and the other benevolent. No idea where exactly that was mentioned though ^^
