Have a Break, Take a Husband

S1, E4: Frank and Betty are taking a second honeymoon, except that Frank is in the station toilet when the train arrives. He ends up having to run for it, manages to grab hold at the back, only to be dragged along the platform until he is eventually pulled inside by the angry guard and returned to Betty. At the seaside resort, the guest-house is somewhat dilapidated and the hapless pair manages to fall through the floorboards, and have to climb through a hole towards the hotel bar to escape.
