Back in the "land line" days (anybody remember those?) I had a friend that would call, and regardless of who would answer, he would say something like "Man with one leg walks in many circles."
The message always got passed to me (often preceded by "that was an odd call"), to which I would reply "I gotta go", and immediately leave the house.
There was only one person I knew that was that odd, and it was a clear indicator that he was now home, so I could head over to hang out. No call ever lasted 58 seconds.
