THis is good use of YouTube by a brand.
And an awesome spoof Rap video... Toyota found a comedy director - Jody Hill and made comedies rather than commercials around a classic sitcom family where every mini-episode is based around the family car.
They also made an awesome spoof rap song... [youtube http://www.youtube.com/watch?v=ql-N3F1FhW4?wmode=transparent]
Basically it's I'm Tha Bosss meets Modern Family.
Nice subtle use of annotations as well.
