Ha! Anyone who thinks British people sound sophisticated hasn't heard most British accents.
In the area I live we speak relatively posh (though to nowhere near the extent we're portrayed on TV), but due to the influence of my scouse mother I occasionally use words like "youse" (plural of "you"), "sound" (as a term meaning "good" or "cool") and "giz" ("give" or "give us"). Hardly sounds sophisticated, does it? And I honestly think your heads would explode if you ever heard a true scouser speak. Even I have trouble hearing that.

This is a worryingly accurate portrayal.
