Well, some of you are pretty close. My family is from Bergen County, NJ - and that's where most of the accent comes from (both of my parents have/had very strong No. Jersey accents as well). You are also correct that my accent becomes MUCH more pronounced when I'm either tired or annoyed
This week I was both - I was working off about 4 hours sleep when we recorded the show, and even though I don't drink, the whole 'you can't share a bottle of wine with another table' thing just had me foaming at the mouth.
