OREO, Milk's Favorite Cookie

OREO had this guerrilla marketing campaign, in which every time the elevator reached the bottom floor, a huge Oreo got dunked into a huge glass of milk. This was so effective that half way through the video you see some guy actually rub his stomach, in what I can only assume, is anticipation of all the OREO's he is about to go indulge in. I know it really makes me want some.
