A Back to Front Wedding - S2.E7

Exhausted from performing several marriages, Father Duddleswell takes Father Boyd to the pictures as a treat -- where they are paged to return to the parish to perform one more forgotten wedding. After placating the angry families and seeing the young couple off on their honeymoon, Father Duddleswell realizes that he performed the ceremony after 6 pm, and therefore the bridge and groom are not legally married.
