A pregnant woman walks into a doctor's office to have an ultrasound. The doctor tells her that she is going to have a little girl. He then asks her what she will name her daughter. She says, "Helen."

He asks her, "Do you have any other children?" And she replies, "Five other daughters, and their names are also Helen."

At that point the doctor asks, "How do you call them all home for dinner?"

She replies, "That's easy I just yell, 'Helen, supper!' and they all come home."

He then asks, "What if you're going somewhere?"

"Thats easy too, I just say, 'Helen lets go!' and they all come running."

He questions her again, "What if you only want to speak with one of them?"

"Well then I just call them by their last name."
