MacKenzieHeartsu

MacKenzieHeartsu is the supposed YouTube username for a teenage girl whose brother, "Brian", uploaded a video to the site in late 2006. In it, she was apparently presented with a red Saab convertible as a birthday gift ... and reacted by complaining vigorously that she wanted a blue car. As a result she was widely referred to as the Spoiled Rich Girl.

The video became extremely popular in the next month, linked to from all over the Internet. It was the lead-in to a series of four followups recorded by MacKenzie herself, in which we saw her move from trying to defend herself to getting the blue car and finally selling the red one. The fourth in the series ended with a link to a Domino's Pizza site, at which point it was revealed that it was a viral marketing campaign to promote the chain's Anything Goes Deal.
