Been meaning to ask this for a while, but today’s probably the last day that this commercial is relevant:
The background is that Dr. Pepper has been co-marketing the College Football National Championship game throughout the season with ESPN. The story line is a parody of a mystery of some type. Every time I watch that ad, the girl screaming “Are you wearing a wire? ARE YOU WEARING A WIRE?” makes me think that it must be a reference to something else in pop culture. Am I right?
