Sorry, no limericks here either, but I do have something to add to the accent discussion.
No matter where I go in the States, people always seem to know that I'm from New York. Now, I would like to point out that I DON'T talk like "The Nanny" or Rosie Perez or any of those, LOL, even though I am NY born and bred. (but I must admit I DO say "you guys" a lot, LOL!)
Once, when I was in Maine, someone said to me "you're the friendliest New Yorker I have ever met!" I guess we do have a bad reputation around here, but we're not really all THAT bad!
