In the episode, high school nerd Gary (guest star Colton James), conjures up a body-switching spell and changes bodies with Sam (Jared Padalecki). Thrilled by his new handsome and built body, Gary (now Sam) investigates a case with Dean (Jensen Ackles) and takes advantage of Sam's good looks and age by hitting on women and getting drunk. Meanwhile, the real Sam is stuck inside Gary's teenage body, dealing with intrusive parents and high school. Also guest stars Sarah Drew (Everwood, Mad Men) as Nora. Robert Singer directed the episode written by Julie Siege with story by Julie Siege, Rebecca Dessertine and Harvey Fedor.
