The Hard Sell  

Advertising: the rattling of a stick in a swill-bucket? Welcome to the show where the stick rattles back: The Hard Sell. Adverts from history, treated with the respect they deserve.
This episode: we ring Pavlov's Bell again with an episode about one of the simplest and therefore easiest to adapt fairy tales in the canon: the one with the frog what's actually a prince and such. You'll be surprised at how many varieties there are: almost as impressive as lager; subject to terms and conditions; actually disappointing; even outright cucked by a breakfast cereal. It's not easy being green! Ribbit.
