This episode is also known as "Scouting Adventures".
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 masked bad scouts (the "Lone Scout, plus One"), who create havoc with their own special brand of 'Bob a Job', where they demand money, or they will do a job (they demand £500 pounds 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.
Deprived of the scouts, Tim joins the Salvation Army (in which he is the only man — appearing as both a Sergeant and Field Marshal). Tim battles the mysterious and masked bad scouts with the help of his all-women troops from the Salvation Army, as well as the all-women troops from the Salvation Navy and the all-women troops from the Salvation Air force.
