We see a well-dress black man finishing off a bag of Doritos in what looks like an office snack room or small kitchen. He holds the bag up to his mouth to pour the crumbs in. Another guy accosts him and stands well within his personal space asking, "Hey, are you gonna finish those?" The black man looks back at him with a look of surpiser or perhaps bemusement since the bag is clearly quite empty now. He says, "Sorry, they're already gone." The white guy responds, "No they're not, you left the best part." The black guy then starts to say, "No, I'm pretty sure they're..." as the white guy grabs the black guy's fingers and sucks on one of them. The white guys says, "mmm cheese" after the finger come out of his mouth.
We pan back a bit to see the black guy shocked and disgusted that his fingers just got sucked on by this random dude. The white guy says, "I love Doritos."
Rock music plays as the screen changes to an animated Doritos logo. Then, we see another office worker, this one is a bit chubby. He's eating Doritos, then wipes is cheesed hand on the side of his pants. The same finger licker guy comes up behind him and rips his pants off. This time he hold the pants close to he face and smells them shouting, "Doritos!"
