I found this site (AUDIOO.COM) via This Week in Social Media (Sean Percival’s podcast) and thought the idea of what they were crowd sourcing was interesting. They say they want to archive more than just funny drunk dials and rage rants. But for now, this seems to be a good start to gather content. Be careful, your next phone message you leave could end up on a site like this and there is nothing you can do about it. 

Found this via @TWiSocialMedia U must hear this voicemail, funny @audioo #voicemail #audioo
