Room at the Bottom (Dad's Army)

Bailey is surprised because there were no commissions in the LDV, and Wilson admits that Mainwaring made himself a captain.

When the parade is about to be dismissed, Mainwaring emerges from the office with a rubber tyre on his shoulders, covering up his badge of rank.

The next day, Captain Bailey returns and tells Wilson that Mainwaring has not even been commissioned as a lieutenant, and he must join the ranks.

Bailey gives Wilson the news in an envelope and leaves via the main hall so as not to disturb the platoon's drilling.

He rushes in and is joined by Jones, who explains that it was Godfrey's rifle that fired, and the two of them help a speechless Mainwaring into his chair.

Mainwaring enters, wearing a private's uniform, nobly declaring that the protection of the town must come before pride.

Suddenly the pre-arranged Drill Sergeant Gregory turns up and immediately starts barking orders, insulting many members of the platoon.

However, Gregory is soon given a taste of his own medicine when they practise sloping arms; Jones mucks it up, accidentally throwing his rifle on the Drill Sergeant's foot.

Wilson realises what Mainwaring is implying, but the latter plays on the moment by saying that he was sure everything would be sorted out, and then says nonchalantly, "Perhaps you'd like to borrow my penknife" (to remove his sergeant's stripes).
