It's called "The Story of Sarah & Juan." The couple meets in high school. Whenever they need to break the ice between them a bit, a stick of gum moves the conversation forward. Singer Haley Reinhart performs a cover of "Can't Help Falling in Love with You," an old love song made famous by Elvis Presley. The agency Energy BBDO and the production company Rattling Stick use the song and the two actors to weave a tight but tender love story in just 2 minutes.
