This reminds me of a gag recording I did for missed calls on an early cell phone. Back in those days it wasn't uncommon to get a recorded error message along the lines of "Wireless Provider error 123: explanation of reason you're getting this error". I recorded a message in my best imitation of the error voice that said "Wireless Provider error 427: The wireless customer you're attempting to contact has passed away. Leave a message and we'll be sure to pass it on to their next-of-kin". This message lasted until the first time I missed a call from my mother, who was understandable very upset!
