Everybody Down - The Navy Lark Wiki

Cuthbert Spinks is the spoilt nephew of Ramona Povey, who decides to spend a few days at sea, in order to try out the naval life before deciding whether to join the Royal Navy.

CPO Pertwee quickly gets fed up of Cuthbert's attitude - refering to the young man as a 'Rude, Crude Prude! - and plots to put him off navy life for good during the trip aboard HMS Troutbridge.

However, instead of putting Cuthbert off, the disastrous trip stiffens his resolve to sign up! This prompts CPO Pertwee to make the best of a bad situation, by tricking Cuthbert into signing on for 21 years service as an ordinary rating![1]
