Attack Of The Little Old Ladies
This seems to be real -- and it's hilarious. The description from K2radio.com:
This guy is leaving a voicemail for his boss when he witnesses a minor traffic accident. A fellow by the name of Michael Childs, said that he was the one who left the voicemail message, that the clip was genuine, and that the accident described took place about six years ago in Athens, Texas, while he was working as a construction manager for Jack in the Box.
