I drove by a house for sale in Watertown today, which had a red sign in the front near the realty sign. It said, in large lettering, "Talking House. Tune radio to 530 a.m." Eager to hear what this house had to tell me, I alertly tuned my radio to the prescribed frequency. The house was emitting a high-pitched electronic shriek. I wasn't sure what type of authority to call for that.
