Wilson and Mrs Pike are having tea waiting for Frank to come home from his call-up medical.
When Frank arrives home, his mother is unpleasantly surprised when he tells her that he has passed A1 (in spite of his chronically bad chest, his painful sinuses, his weak ankles and recently acquired nervous twitch), and has requested to be put in the RAF.
Hodges arrives to rub it in to Mainwaring, but is interrupted by Corporal Jones, who states that he has been down to the POW camp and gathered 80 Italian soldiers.
Hodges states that he still wins because he reached his target, but Jones replies that he has not, as he has also brought down seventeen nuns.
Then, Pike adds that because of his rare blood type, the RAF will not have him and so he is not leaving after all, and the reason he did not want to tell the platoon straight away is because he had never had a dinner in his honour before.
