In one of the flashbacks, Lemon (Jaime King) mentions that the baby Jesus in the nativity set is missing an arm. This is a hidden reference to an episode of Gilmore Girls (2000), where the baby Jesus in the town nativity set was also missing an arm. What makes it even more ironic is that both shows were filmed in the same town square setting.
Although Meredith Monroe plays character Lemon's mother, the actress is only ten years older than Jaime King. This came about because Monroe was first cast to play Lemon's mother only in flashbacks.
