Play Random Sounds for E-Mail Notifications?

An anonymous reader asks: "I, like many of my fellow Outlook-using geek friends, like to set funny sounds to be played when a new message arrives ('Leeroy Jenkins' is the one I have set now). However, we have always wanted to be able to have random sounds be played when a new message arrives, rather than the same sound over and over. I've searched high and low, and I was hoping Slashdot could suggest/write a program that can randomly play sound files from a specified folder when a new message arrives. Any ideas?"
