Who knew

I passed the Verizon Center (which, for out-of-towners, is a concert arena, not, for example, mom's favorite customer service center this side of the Ganges) on my way from work to happy hour, and there were hordes of screaming teen girls in miniskirts (but they looked respectable, not trashy, like, say, a GT undergrad). Then, on my way to the metro from happy hour, there were even larger hordes of screaming teen girls-- and I mean screaming-- emerging from the metro. I asked one of them what was going on. The Spice Girls, apparently.
