I used to get this call when I lived in San Francisco: the phone rings; I pick it up and say hello. The person on the other end makes this totally bizzarre sound like a deaf person trying to speak. The person would repeat certain utterances, and all I could say was "huh?" or "what did you say?" After a few minutes the person would get agitated and hang up. A year later I would get the same call. This was an on and off thing for about 4 years. I attempted to communicate with the person, but it was impossible. The last few times "it" called, I answered very cheerfuly, like I was talking to an old friend. This made the caller even more flustered.

I guess you had to be there.
