The Family Way (1966)

Following the wedding of young Jenny Piper and Arthur Fitton (Hayley Mills and Hywel Bennett), a rowdy reception is held at a local pub where the newlyweds are subjected to much well-meaning but vulgar ribaldry. The couple returns to the Fitton home to spend their first night together before leaving for a honeymoon in Majorca, but they are followed by some of the wedding guests who keep the party going until early morning. Worse yet, when the youngsters finally are permitted to retire, their bed collapses as the result of a practical joke.
