Dad's Army (1968)

Season 4: Episode 12

Once more, the civic vicar's hospitality for both Home Guard and ARP forces the rival corps' men to cohabit in the church. This time, Mainwaring and Hodges even have to share the vicar's desk at the same time. Their men try everything to push the others away, and end up lighting the chimney so ineptly that the church tower catches fire, making it a prime air raid target. As that would render them the laughingstock of the county, they decide to put out the fire on their own, with their usual mixture of bravery and utter bumbling incompetence.
