Something else from yesterday... I had the good fortune of witnessing two African American teens attempting to convince two visiting Japanese girls that they were, in fact, Michael Jordan of NBA Fame and Ruben Studdard from American Idol. This was made better by the fact that the girls spoke broken English (at best), and then better still because neither seemed to have any idea what either the NBA or American Idol were. They just laughed and nodded a lot, much like the rest of us in the car. Seems the notion of "I don't fully understand you, but I'm getting the feeling that you're full of shit" is pretty universal.
The exchange was not entirely fruitless, though. By the time the girls got off the train, they had a working understanding of the proper use of bling bling even if their pronunciation was a bit off.
