I can’t link to it directly (f-bombs droped), but there’s the amusing “Baltimore accent test” on Youtube (originating on Reddit, apparently) in which several people try to say “Aaron earned an iron urn” with mixed degrees of success.

If you go from one end of the American south to the other, you’ll hear about 5 distinct pronunciations of “praline”, some of which include consonant sounds for letters not found in the word.
My home city (NOLA) has some interesting takes on things as common as “sinks” (starting with a “z” sound) and mutilation of mythological names of the 9 greek muses (they’re used as street names). Interestingly, despite

Anothe good one to look for: back when Eyjafjallajökull was erupting, a travel segment crew went to Iceland to get educated on how to say it properly, since so many non-Icelandic speakers were struggling with it. One man broke it down very well, but then mocked others for having so much trouble getting it straight, The interviewer got him back by asking him to say “sausage”, which he failed to get that “edge” ending, instead frustratedly storming off camera saying it like “sausish”.
