Boy Scout

When the Fifth Doctor produced a penknife from his pockets on the planet Samur, Tegan said that she'd always suspected him of being a Boy Scout. This caused the Doctor to respond that he "always tried to do his best". (AUDIO: Heroes of Sontar)

Ian Chesterton claimed the Horsehead Nebula in the Earth sky looked like "a boy scout's badge". (PROSE: Byzantium!)
