This means that Petsi Pies, my friendly local pie shop, has stocked up its inventory for the rush on the delicious round things, a rush which I gather is quite intense.
I believe that Petsi recognizes a correct recital of the first 10 digits of Pi with a slice of pie, whereas a correct recital of the first 100 digits of Pi gets you a whole pie. Of course, it takes a while to get through 100 digits of anything, so expect longer lines today.
I file this under, "Living in Cambridge", even though this particular Petsi Pies is just over the line in Somerville. Regardless, it's part of what makes this place wonderful.
