Don't you be dissing the duck that just happens to be my ring tone it is so funny in public to pick up a phone that i quacking and saying hello I love it!
I don't like to attract attention in public, so I prefer the regular phone sounds to the funny duck sound that makes people look and go "ooh, an iPhone!"
Besides, I carry around a real duck on my head at all times, and it's one heckuva quacker. So if I set my iPhone ring to quack, and I start to hear quacking, I wouldn't know if it was my iPhone ringing, or just that darn duck on my head getting mouthy!
