While cooking, a burner holding a 10-gallon(?) pot of boiling water was knocked over. Miraculously, the pot fell to the table without spilling any water; the burner, however, landed on the floor upside-down. There was a large flash of flame, and now the carpet has a rather interesting spiral design in it.
Update: In an unsurprising move, Facilities and Maintenance participated in a coverup of this fascinating piece of anthropological evidence. A careful inspection of the carpet shows a slightly miscolored (i.e., clean) patch of carpet marking the place where the LoungeCropCircle once reigned supreme.
