You've heard of those foreign foods and companies which don't translate well into English and would never sell anything here-- like the nutty snack bar called c***. There is a Chris Tarant show which shows adverts for such things on the ITV network in Britain.
Well I've discovered that there is an Italian company called Smeg which makes cooker hobs, dishwashers, ovens, refrigerators, etc. I, for one, would stay clear of a Smeg household appliance. I tried to find out if they made a Talkie Toaster, but unfortunately there's no demand for one, that's probably one thing that they would sell.
