Graeme and Bill are curious — Tim has been acting in a suspicious manner. They decide to follow Tim, and find that he is a scout, with the name "Brown Owl". Bill and Graeme are jealous of him — they want to be scouts, too. So Tim allows them to join — however, their behaviour is so bad that they are quickly drummed out of the Scouts by Tim.

On the outer, Graeme and Bill become bad masked scouts (the "Lone Scout, plus One"), who create with their own special brand of 'Bob a Job', where they demand money, or they will do a job (they demand £500 from Tim, and then £1000 from other people). They also cause problems for people as they work towards getting their Wig-spotters Badge and World Domination Badge. Graeme comments to Bill that there are only three people who had ever received the "World Domination Badge" — Alexander the Great, Julius Caesar and David Frost (although, Graeme says, David Frost had actually pinched his badge). The actions of Bill and Graeme result in the Scouts becoming an illegal organisation, and Tim and the other scouts are forced to hide their scouting membership from the Scoutfinder General.

The Scoutfinder General decides to trick Tim into revealing that he is a scout, by saying: "Dyb, Dyb, Dyb," with Tim then joining in with: "Dob, D-shhhhhhhhhh!" The Scoutfinder General asked sharply: "WHAT WAS THAT?!" to which Tim replied nervously: "N-nothing."
