Heh. I think that Cricket and Baseball are there soley to confuse foreigners with the arcane rules.
I find it interesting that you say American accents are perfectly comprehensible to Brits. Truth be told, when I speak with someone from England, I often have to concentrate rather hard in order to make sure I understand them.
And this is after watching lots of English actors on TV and in movies. There's something about the way "real" Brits speak in regular conversation that's different than the way Brit actors speak. I don't know exactly what it is. Maybe it's that all of the famous actors from England are all from the same town or something, and I've just gotten used to that regional dialect. Or maybe they all went to acting school and were taught to carefully enunciate every word when on camera.
I mean, it's not as bad as say, watching Brad Pitt in "Snatch" (I don't think most English people even understood him), but it's kind of like that. I think a better analogy would be when they made fun of the Scottish accent in "Chicken Run" ("Was that English?"). I honestly feel that way sometimes.
We're renting our second house to someone from Cambridge, and the few times I've talked to him, I've run into this problem a little bit. And of course, occasionally when I talk to you guys I miss a word here and there.
