Dr. Harris was an OB/GYN that Piper Halliwell had an appointment with about a fertility test. When Phoebe began to experience unusual symptoms during her pregnancy, Piper gave the appointment to her instead. Dr. Harris noted that she really should have seen a doctor earlier. When he attempted to do an ultrasound, the fetus attempted to "defend itself" due to the cold gel and proceeded to electrocute the doctor. Piper quickly froze the confused doctor and the sisters quickly left, presumably coming up with some sort of excuse.
