I remember joking around with some British friends telling them I have to work on my British accent before I visit.  They just laugh and ask “which one?”  I imagine they are correct because if they said they need to work on their American accent, I'd ask which one as well.Here is a list of the most popular British accents.List of Cool Accents 2008/9 1. Queen's English 20% 2. Scottish 12% 3. Geordie 9% 4. Yorkshire 7% =. Cockney 7% 6. Northern Irish 6% 7. Welsh 5% 8. Scouse 4% = Mancunian 4% 10. West Country 3% 11. Brummie 2% We probably wouldn't even be able to tell the difference between some of these but I'd be willling to bet they can tell who is from Liverpool and who is from Porstmouth.
