Besides Sir Mix-a-Lot and a handful of uptight teachers, people loved this campaign. Millions viewed it on YouTube, thousands downloaded the ringtone (Carl's Jr.'s most successful ringtone to date), and the song became water-cooler talk all over the airwaves and the blogosphere.

Check out the longer :60 radio spot that started it all, our intentionally-amateurish “flat buns enthusiast” site (which was referenced only in a lyrics of the song) and the funFamily Guy video mash-up/cross-promo.
