Agency party planning? AND PONIES??

So this is one of the sillier posts I've seen. The Canadian ad agency, John st. decided to make a parody 'disruption' video of sorts. The mission? Advertising agencies planning kid's birthday parties. With lines like "research shows that eight year old Chelsey likes the color pink, and ponies." I think I just about died when the "traditional techniques" (pin the tail on the pony) was thrown out.
So what is the message behind this birthday movement? Is it a message of how out of hand this industry is and how deep we have infiltrated the culture? Or is this simply a silly video to pass the time when procrastinating around the office? Many interpretations are out there. Personally, this reminds me of a video that our marketing professor made us watch about a year ago titled Consuming Children. A sick film, really. It did help open my eyes to what a glutinous monster marketing can be. I suppose this is slightly better because there were no Barbie logos anywhere to be seen.. Or maybe this video was worse because the J.B name was dropped.

I'm still left wondering why the mini pony at the end of the video wasn't pink... I guess dying a pony the color pink for Chelsey's eighth birthday party theme would be a little sick.
