Includes an educational procedure for pedestrians to cross streets safely. The "look right, look left, look right again" mantra came from a Royal Society for the Prevention of Accidents campaign in 1936. Around the same time period when this episode was shot, The Green Cross Code, created by the National Road Safety Committee (now the Royal Society for the Prevention of Accidents) to raise awareness of pedestrian road safety in the United Kingdom, was established. The multimedia Green Cross Code campaign began in 1970 and continues today. The Green Cross Code replaced the earlier Kerb Drill pedestrian safety campaign; the Kerb Drill's military style ("Halt! Quick march!") was deemed confusing to children by safety authorities.
