Bedlam in Beantown. Here's the dispatch from our man on the ground, Samer, rendered into singable lines through the atomizing magic of chat:

people are going crazy
one girl was determined to flip the T
she kept starting chants
everyone was happy
there was a cat in a superman costume
but that was the best
it was like a new rally squirrel
some guy held up it up like simba
and everyone around him chanted "supercat"
that's pretty much my field report
