<human>: Obligatory "didn't happen today", happened a couple of years ago.

I was babysitting a little girl while her parents went out to dinner. It was almost bed time, and I was trying to pass the time, so I turned on some music and we had a dance party.
Before I go any further, I'm going to tell you about their giant ass golden retriever, who they had not neutered. If it moved, you better bet your ass he was going to try to fuck it.
Anyway, we are dancing, minding our business, having a grand old time when this mother fucker comes barreling around the corner. He's got his horny little eyes set on the little girl. He runs into her full speed, knocks her down and just goes to town. We both scream, music stops, dog is still debasing himself. I run over and wrestle the girl away from the dog, pick her up and run. 
Mother fucking mother fucker thinks it's a game now. He gives chase. 90 pounds of golden retriever jumps me. I hit the ground and the little girl slides out of my hands and across the floor, stopping herself with her face against a planter. Now there is blood everywhere, a crying child, a crying teenager, and a dog that is completely oblivious to it all, now humping me. 
I ninja kick the dog off me, pick up the girl, and apply pressure to the gash above her eye. I call her parents, but of course they don't answer. After numerous unanswered phone calls to mom and dad, I decided to call my own parents. They live a couple blocks away and they could help. Phone is ringing and my sister picks up. "Welcome to McDonald's, may I take your order?" 
She then refused to give the phone to my parents unless I told her what was wrong. Finally I get to talk to them, they come help, girls parents then come home and take her to the hospital where she had seven staples put in.
