Sherrie87 asked:
Is Meat's exagerated US Southern accent lost on native Brits? He sounded like a crazed televangelist.
I doubt it

We're generally I suspect better at distinguishing different American accents than Americans are at identiying British regional accents .. and better at understanding them than you would, say a Geordie, a Scot or a cockney.. didn't they say that many people in the US couldn't follow what was being said in the Full Monty? .. and that was just the Sheffield accent ..
Quite apart from the amount of American TV we have broadcast, a pretty fair percentage of Britons will have visited the US .. so most of us would recognise a deep South accent and possibly even distinguish it from the softer Carolinas .. and certainly associate it with evangelists, particularly the tv variety .. who was it that said "If God does decide to send a personal message to the world he will NOT choose a balding overweight man in an expensive suit from the deep South of the USA to deliver it!! " .. :)
But Meat can certainly portray one with some considerable skill!! :)
