"Oh did I just shoot your husband?" asked the Robber sarcastically. "If you want me to I can put the dog out of his misery." He prepared his gun to shoot again.
"You are not gonna hurt him!" shouted Mary.
"Why what are you gonna do you over grown freak of nature."
The robber seemed to have hit a nerve in Mary. She moved towards him so fast that he didn't have time to react. She pulled the gun from his hand and threw it to one side. Then she picked him up by his neck and made him bang his head on the ceiling. He then went unconscious. Then she went over to Ted.
"Oh my God Ted are you alright?" asked Mary.
"No not really I've been shot in my leg," replied Ted. "But with medical science today I'll be fine."
"Oh Ted you'll be fine." She then hugged him. Then she heard sirens outside.

What was it?
