Dayam, but you're right! The fact that it was an Irish accent went right past me because it wasn't over the top on the accent. D'oh!

However, Northern Ireland is part of the United Kingdom of Great Britain and Northern Ireland which is made up of England, Scotland, Wales and Northern Ireland. We (in the US) commonly call all of those Brits whether technically correct or not.

Now the Republic of Ireland is a different kettle of tea. Call them a Brit and you'd probably get hit over the head with an empty pint of Guinness. No decent Irishman would EVER waste Guinness by hitting you with a full pint.
