I have one on an old phone that I don't use anymore...I got it in Germany and it is translated to f____ing squirrels. It is hilarious about the first two or threes times you hear it and then it turns into a head ache. So it was my ring tone when I was in an airport and for my voice mails so I would realize that someone had left me one. It really set me apart from the crowd as well since no one else had that ring tone over here.
I also have another one that is a very sultry voice of a woman that says "You have a call." That one sets you apart as well.
