Is your local town or village pronounced completely differently to how it is spelt? There are plenty of them like that in the U.K.
The town Wymondham in Norfolk comes to mind, pronounced Why-mun-dumb.
Agreed, Shaneystar2. Most definitely not Why-mun-dumb! (It was 'Windum' College that we played at cricket when I was at school and it's 'Windum' where I've got frozen to the core doing traffic surveys in more recent years).
Around here we've got Sproughton (pronounced 'Sprorten'), Debach (Debidge) and Happisburgh (Hazeburra) among others.
There are some locally-used names which those who use them will readily agree are simply 'slang'. (For example, most people asking a bus driver for a ticket to Doncaster would probably just say 'Donny, please').
But there are other places where arguments rage among the localsabout the correct pronunciation of the name. (For example, the residents of Hunstanton seem unable to agree as to whether the town's name is pronounced as it is written or as 'Hunston').
I lived in War-wickshire for a couple of years, Captain2: Kersely, Coventry. Anyway, it's wooster sauce; no, it's worchester sauce; or could it be worchestershire sauce; maybe worchestershirshire sauce.
