In reply to JimR:
So let's get this sterotyping pinned down:
Brummies - funny, not to be taken seriously
Scousers - robbers, shifty
Geordies - fat, thick - though accent is musical
Mackems - like Geordies but with brains bashed out
Smoggy - like Mackems but brains turned to mush by poisons from local
industry (all gone but lingering effects)
Glaswegians - violent, unhealthy - eat mars bars in batter
Londoners - limp-wristed, decadent
Woolly-backs - thick though make dependable servants
Welsh - sheep worriers, though can sing a bit
Scots - parsimonious, anal
That'll do to get us going.
