Great thread!
My favorite story came from when I was prepping to move here. A friend of mine happened to be moving to London around the same time as I was, and her very concerned sister (who is an adult, whose own mother is from the UK), asked us if they had tampons over here!
While on my MA course, I've met a few other Americans that have come over here. I find it funny that some people just make no effort to learn anything when they move over here, because they know they aren't staying. After a late night of working, I walked into the tube with a fellow American dude, and he just stood staring like he had never seen public transport before. I asked him which area of London he lived in, he knew the name, but had NO idea whether he lived in North, South, East, or West London. North or South of the river? nope! How long had he lived here? TWO YEARS.
