Unfortunate Switch

A blonde goes to the doctor with burns on both of her ears and her right hand.
“Sit down and tell me how it happened,” says the doctor.
“I was ironing my clothes when I received a call. Instead of picking up the phone, I picked up the iron and burned my ear.”
“What about the other ear and your hand?” the doctor asked.
She replied, “I tried to call for an ambulance.”
