Michael Rosen questions whether we change the way we speak according to the social class of the person we're speaking to. Novelist Graham Joyce has had an interesting experience with language throughout his life, moving between classes, as has critic Stephen Bayley. Linguists Julia Snell and Vineeta Chand fill in the detail. And the programme features archive clips of comedy making full use of the rich comic potential of this way of behaving.
