When I was in high school we took our senior trip to St. Louis Missouri. At the base of the "Gateway to the West" arch, one of my classmates, an odd fellow named Chris, started to trot up the stairs. It wasn't just that he was running up the long staircase, it was that he was plopping along like a, shall we say dimwit. There were a dozen or so of us watching from the bottom of the hill, and we immediately broke into that familiar theme. Na-na-naaaaah. Na-na-nah. Du-du-na-na-na-naaah (to the tune of Gonna Fly Now). You know, the one people always hum when they run up a large flight of steps.

So here we are, a bunch of geeks singing the Rocky theme as Chris made his jaunt (ala special olympics style), up to the top of the steps of the St. Louis arch. Then something amazing happened. Many of the other tourists had noticed Chris' stunt, and feeling inspired, joined in as well. First it was just one or two, but then several more couldn't resist the amazing pull of the Rocky theme song. By the time Chris reached the top and turned around with his fists up in the air, there were literally hundreds of people singing the Rocky theme. Geeky as it may sound, it was still the largest spontaneous musical display I've ever seen. It's the stuff you think only happens in movies.

But apparently, for some inexplicable reason, they do it in Philly too.
