Punch ...8,9,10 he is out, or not?

I was in the kitchen and I am not clear what sparked this other than sounds like fun. My son Gunnar who is 6 at 70 pounds and an avid wrestler was laying on the couching reading a book. My 9 yr old daughter Molly weighing in at 54 pounds decided to do something dumb but fun. I look over and I see her standing on the top of the arm rest at the other end of the couch were Gunnar was quietly reading. As I was trying to figure WTF, I see her launch her self in a sprawled eagle style toward Gunnar, sort of like they do off the top ropes in WWF. I here a thud as she lands on top of him. With the back of the couch to me blocking my view, all I can see next is her arm and fist rising and falling over and over above the back of the couch. I think Gunnar was so engrossed in the book that the first 2 or 3 punches he would have ignored but no, she did a rapid 5 punches which was enough to trigger his "Hulk" mode. She springs off of him and is making a mad dash toward me. Gunnar comes up with fire in eyes while grabbing the Calamine spray can. Sssssss as closes in on her, he leaves a trail of lotion on the couch. Molly hugs my leg for dear life like that is going to stop his head lock he now has her in. I finally get him in a full nelson and get him quieted down. Later on I ask Molly, WTF, you know he can hurt you bad, "I know daddy but it was fun", sigh.
