In one of Richard Espy's books is a passage in rhyming slang - I can't find it myself, unfortunately, but I remember 'Down the Frog' as a lot of fun - I have no idea of the authenticity of "taking the cherry down the frog for ball o'", but I it was a lot of fun to read. Has anyone got the original text - it's only one paragraph.

I grew up using a lot of words which I had no idea were rhyming slang - I only found out later. In particular, (and you can save this up for the next coronation) 'take a butcher's at that titfer' used two that were routine, as was scarpa (which I used to spell scarper, assuming in my childish way, that it was a perfectly ordinary verb in english...)
