I get relentlessly mocked for pronouncing 'squirrel' with the middle syllables slurred! My sister does too, and we've confirmed that yes, it's not an us-thing, it's a North American accent thing.

Also, I can't say Cairns properly to save my life, if I say it in a way that ought to make it sound right with an Australian accent, it comes out fucked up. This drives me bats.
