Four-year-old Hardcore Dancing to Four Year Strong

My little sister let me a take a video of her hardcore dancing to Four Year Strong and, after watching the videos, told me I should put it on You Tube. Yes, I have her consent to be put on You Tube :)
Secondly, yes, I taught her how to hardcore dance, but no, I do not like hardcore dancing, I think it is retarded. I tried teaching her moshing, but she didn't really understand it as well as this, so I thought I might as well do this because it is still funny.
