Somebody has left a white 'CHEMIST'S' paper bag with a GREEN CROSS on it, underneath my window today...

What does that symbolise?

No idea...but we have been circling BIG PHARM quite a bit...

The Green Cross Code Man

The Green Cross Code Man (sometimes known simply as "Green Cross") is a costumed superhero character created in 1975 as an aid to teaching young children the Green Cross Code, and for promoting general road safety. British actor David Prowse MBE, a bodybuilder and former Mr. Universe (and the actor best known for his portrayal of Darth Vader in the Star Wars films) is famous for his realisation of the character in a well-known series of Public Information Films (PIFs) sponsored by the Central Office of Information for the UK Department of the Environment. The light-hearted spots ran on UK television from 1975 to 1990. In the films, the Green Cross Code Man character has the power to teleport from his monitoring station at Green Cross Control to any location where youths are in need of pedestrian safety instruction. He accomplishes this by use of a wristwatch-like "Dematerialiser" device. On these missions he is sometimes accompanied by a whimsical robot companion. His signature exclamation of surprise or disbelief is "Green Crosses!" and his slogan is "I won't be there when you cross the road / So always use the Green Cross Code." John Yorkston the chairman of Dunfermline Athletic Football club was the man pipped at the post for the role by Prowse. The Green Cross Code Man, played by Prowse, was later to guest in an episode of BBC2's Fantasy Football League - a Phoenix From the Flames recreation of a goal by Gerry Francis in a Home International against Scotland (the main premise being that Francis tended to look from side to side during interviews - as was advised by the Green Cross Code Man in his adverts).
