Cockney rhyming slang/Talk

I'm at work so I don't have time to address this right now - but this article focuses a little too much on CRS in East London, and fails to explore the way it has spread across the world. CRS is very common in Australia, and has even turned up in the US - eg. the term "Raspberry" for a fart, derives from "raspberry tart" (source: David Crystal - The English Language). It's still a very good article though - just needs a bit more depth. - MMGB
