For a while I had the ring tone as an AK 74 firing. I really liked that one until HR told me I had to change it. So I recorded my then 8 year old daughter saying "Hey, some fool is calling you". Another conversation with HR. That lead me to talk to a neighbor at the time who had one of those guitar pedals that make the guitar talk (like Peter Frampton or Joe Walsh) saying "Answer the GD phone", except he filled in GD. Yet another visit to HR. The last ring tone while I was there was me shouting "Nobody be offended, it's just a phone call". Now it's the Mario Bros. theme when he's in the underground.
