I hear so many different songs on people's cell phones -- and I'm embarassed to say I don't recognize most of them. Sometimes I'm not even sure if it really is a phone ringing or a radio.
So I decided to top them all. My ringtone is the good old "Brrrng" of a Ma Bell rotary phone. The depressing thing is I could have sworn when my phone ran gat the airport I heard a kid say: "What's that noise?"
