Sadly, it's not “Summer Girls.” So how did the cast become involved in this music video? Landon Pigg (of Falling In Love At A Coffee Shop” fame) happens to be the boyfriend of cast member Mae Whitman (of “Arrested Development” and “Scott Pilgrim” fame).
In the video, Mae plays "The Girl On The TV" which only leads me to believe that Landon Pigg fell in love with her ...while watching TV. The only appropriate thing to say to that has to be, "HER?"
