Was that shot-for-shot between the two? Or was this clip just grabbing all the pieces she's done and lining them up with the music video? Regardless: ouch! At least the internet has spoken.

looks like its about one minute taken from two separate videos she did that total about sixteen minutes and then pulled one minute of dancing from 1440min(24 hrs) of dancing video done for Pharrels Happy Video. Shes only using the clips of Pharrel which were actually taken from his music video.

(she actually may have pulled her clips from much more video http://girlwalkallday.com/watch-the-film/schools-out)

Meh im guessing lots of videos out there of people dancing in the street could do the same when using 24 hours of dancing footage. Much better argument if all the footage was from his three minute Happy video.

I agree with @eric3579.

It would be easy to find similarities when taking from a video that is 24 hours long. Also, some of the examples were a bit of a stretch.

Moving this video to bareboards2's personal queue. It failed to receive enough votes to get sifted up to the front page within 2 days.
