"dumb Polack"
This was maybe in the 70s and before, now you don't hear it at all. I've never been called a dumb Polack.
Sometimes people will hear me speaking Polish (outside of Chicago since there everyone knows a Polish person) and ask where I'm originally from. Or they'll ask something stupid like is that French you're speaking? German? Sometimes a sharper person may ask if it's Russian. But French or German... come on... they sound nothing like Polish.
A few times people, mostly the **** kicking redneck dually pick-up driving types who think it's appropriate to wear overalls out in public, will say something to the extent of "This is America, speak English!" To which I usually respond something like do you know any languages besides English, are you bilingual let alone trilingual, to which they reply no, and I'll answer something like I pity your lack of culture and world experience, that's really unfortunate all you've experienced is America, or something similar.
40% of Americans don't know who the veepee is now.
There's a few youtube movies of people being asked simple questions like how many states are in the US, where is Iraq, what's 10 squared, etc. My favorite is "if you're going 80 miles per hour, how long does it take you to travel 80 miles"
