There is an Australian performance artist had a third Ear surgically implanted in his arm

Stelios Arcadiou, also known as Stelarc to his fans, waited years to find a doctor who could graft an ear onto his arm! He says that it is an artistic augmentation of the body’s form. Of course, Stelarc is not able to hear out of this extra ear, but he hopes to one day implant a microphone inside the ear so that others can listen through his arm!
