Dad's Army 1970 S04E12

Episode: Uninvited Guests. 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 captain Mainwaring and chief warden 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 laughing stock of the county, they decide to put out the fire on their own, with their usual mixture of bravery and utter bumbling incompetence.
