My favourite is a Norfolk accent - reminds me of my Norfolk granny.

The interesting thing is, why do different regions have different accents and why are such accents so constant in those regions? It would also appear that most people can't acquire another accent after a certain age. For example, I've lived in Manchester for nearly two-thirds of my life but still retain my native Peterborough accent ("are y'all right, mate? Did'ja come on y'bike?" - 'right' and 'bike' with a trace of an East Anglian 'oi' sound).
