Eh, in a weird way, this reminds me of when I read comics. When I'm reading someone's dialogue, I have a voice for them in my mind that I think they should sound like. So reading something like X-Men is kind of crazy for me, when you have all kinds of mutants from different parts of the world, trying to read their dialogue and imagining their accents gets pretty distracting. Irish and Scottish are the toughest for me, for some reason. So Moira MacTaggart and Banshee dialogue really distract me from what I'm actually reading, since I'm focusing too much on what they "should" sound like to me, and less on what they're actually saying. And forget about Carol Danvers...I just imagine a plain Midwestern accent for her, since I can't even begin to put a Boston accent in my head. Haha, I'm pretty sure this all sounds really stupid.
I once got stuck doing some weird half-French-half-German accent an entire day at work a few years back.
Heh, any time I try to joke around and say something with a French accent, it usually ends up sounding German.
Also, going a bit off-topic again (sorry), have you ever joked around in an effeminate voice and had someone say, "Wow, you do that a little too well"? I always thought that was a dumb thing to say. If I was doing, say, a Russian accent instead, would they suspect I was actually Russian? Pfft.
