how to freak out an advice nurse

Liam was sick yesterday so I called the advice nurse.  We were talking for a while when Liam started playing with his VERY loud fire truck toy right next to the phone.  The nurse freaked out and thought that I had called an ambulance to the house.  Oops.  Needless to say, (after I spent a few minutes calming her down, she should cut out caffeine) she was quite relieved that the noise came from a toy.
