Dorothy says "Call the Midwife has like 13 seasons". The events are taking place in 2019, when Call the Midwife was on its 8th season. Of course Dorothy could have been mistaken, or using hyperbole, or it is possible that in the Fargo Universe, Call the Midwife could have been on its 13th season in 2019, but still, worth noting. Interestingly, when the episode aired, Call the Midwife was on its 13th season.
