Apparently I sound Irish. I get this all the time from people who are from the same town as me ¬_¬ Maybe it's because I don't speak like I have a pie jammed in my mouth that they don't get my accent. Not that I have much of an accent, or at least compared to most people here.

Try looking at trailers for films for different accents. Some of them can be a little put on, but they're about as accurate as you're ever going to get from something that's been recorded for entertainment rather than recorded from real life.
