Came across this one by accident.
Originally I was trying to find a connecting tone so distressingly out of fashion that people feel painful every time they try to call me. I ended up choosing a depressing little ballad from the 1940's. But then there must be some software glitch at the mobile operator, and now people get complete silence when they call me. Silence... and then more silence... and then out of the blue I pick up and growl hello (or I cut them off). Coolest ever.
I hope they never get around to fixing this glitch.
