It was another 'sign' of the times at a certain office building in L.A. today, as I stumbled across a sign in the lobby, right by the security desk. The last sign I found, back in November, was in the Men's Room. It warned against drinking water out of the urinals or toilets. This sign was even more provocative. "Methane Control Panel Interface Inside," it said. "Excuse me," I said to the security officer on duty, "I can't help noticing that sign beside you. Is there methane around here?" "Oh yes," he replied, "Oodles of it." "I see," I said, "So what does the control panel do?" "When the levels get too high, an alarm goes off and I can use the control panel to monitor the situation while we evacuate everyone," he replied. "Thank you. Then I know what I must do," I said, "I'm off to the men's room to drown my sorrows in a refreshing glass of toilet water ...!"
