Let’s jump forward two series to the fifth season, and back to Mr Blewitt (presumably his brother is at peace by this stage) who was probably not expecting the late night visitors he received after taking possession of a suspiciously large chicken, courtesy of Jones’ butcher’s shop.

The trouble is that this particular chicken, just possibly, contains £500 that Cpl Jones should have been taking care of for the town Spitfire Fund. And so it becomes a matter of vital military importance that the chicken should be thoroughly inspected, in the small hours of the morning.

Like a number of the Dad’s Army cast, Harold Bennett was great at reactions and his bemused irritation at being disturbed in his dressing-gown on such a ridiculous subtext is wonderful – as is the way Arthur Lowe manages to deliver some truly ridiculous lines with a straight-face.

50 Moments that made Dad’s Army is a series of blog posts each focusing on one moment that helped define the popular comedy series. There will be one post for each of the 50 days leading-up to the 50th anniversary of the first broadcast of the first episode of the series on 31st July 1968. 50 Moments that Made Dad’s Army is brought to you by walmington-on-line.co.uk and copyright of all video clips belongs to the BBC.
