Clear your calendars this Saturday night: it's time to fluff.

That's right. Fluff (not fluffing...) was invented right here in Somerville, and they're damn proud (as they should be). Union Square is celebrating the 90th anniversary of the invention of marshmallow fluff, complete with go-go-dancing Flufferettes, a fluff lick-off, and fluff cocktails. Hey, didn't the Rainbow House have this party last semester?
