Years ago, when I was still living with my parents but had my own phone, I had a pretty good one. I had an ambulance siren (from a record of sound effects) in the background, and I said, “Hi, this is ____________, They’re coming to take me away now. If you want me to call you when I get released, leave your name and number at the beep.” Then I turned up the siren until the end of the message.
The funny part was there was an immigration court judge who was apparently giving out business cards with the number misprinted – and it was misprinted with my phone number. I sometimes got several calls a day from lawyers who were very confused when they heard the message on my machine!
