Johnny English means in slang: After accidentally becoming indirectly responsible for all of the agents’ deaths, a clumsy MI7 secretary was promoted to secret agent. Johnny can be careless, impulsive and clumsy but his extraordinary self-confidence, along with his sidekick Bough, usually gets him out of trouble. He is a supposed “man for all times” and accidentally becomes King of England. This happens after his attempts to stop the main villain have failed massively.
