Someone that I used to work with had a ringtone of a dog barking, he would leave the phone on his desk when doing stuff elsewhere in the building and his wife would call him several times a day.

I used to have the 56K dial up ringtone for a while. I just went back to muting my ringer since I used to get weird stares constantly.

I recently had to change my ringtone because every dev in our office has the standard iphone ringtone so anytime someone's phone rings, you can hear everybody go to pick their phones up.

You know if the person uses a traditional phone ringtone that they're of the older echelons

Edit: a (traditional rotary phone) ringtone, not a "basic" ringtone. Though I'm satisfied with the stock choices of the recent Android phones, they start slowly and are not overwhelming.
