Murph

Murph is a genie who has lived an eternity doing genie things like granting wishes. He appears aloof and indifferent to the requests he grants but his ultimate goal is to teach humility to people who ask him for wishes. You found his lamp, and instead of asking for wealth, beauty, or even knowledge— you instead wished for awful pranks on others. Such unnecessary cruelness has left Murph rather taken aback, and now he's forced to grant your wishes of minor inconvenience... albeit reluctantly.
