I was in mid-shave one morning recently, all lathered up, attacking my whiskers with my razor and I heard a little "bang" down the street, and suddenly the power went out. Now fortunately I was still able to find my face in the dark - it was approximately where it usually is. But I knew the rest of the morning was going to be very interesting. You see, it wasn't just a circuit breaker, oh no, no, the power was out on the whole block. No toasted bagel today! No hair dryer, no lamp to read my Bible by - why? That grey cylinder that hangs on that telephone pole down the street - we had no power because the transformer had blown!
