Jim Davis has given Jon Arbuckle (and Garfield, the fat feline) cell-phones. These cell-phones don't tring-tring or beep beep. They beedle-beedle-beedle.
My current cell-phone allows me to use any peice of music (any mp3) as a ring-tone. It allows me to use a midi of Beethoven's ninth (that I can download off the internet). It has that "I like big butts" disaster built in as a ring tone.
But when one searches for something that sounds like a phone ringing, alas, my cell-phone does not even get as close as beedle-beedle-beedle. The best I can do it that ghastly tune that at&t bundles every phone with.
I have toyed with the idea of tweeting into the phone (tring-tring). But I suspect that it would be extra-embarassing - so I won't do it. I could get one of those birds to tweet into the phone and record a ring-tone. But (a) Birds have an understandable tendency to wing it when one makes oneself proximate to them (b) Even if one does (somehow) manage to sneak up to a location close enough to one of those birds to record a statement, birds are remarkably recalcitrant.
Technology has scored one over me. It is almost impossible to install a respectable ring tone on my cell-phone. I shall enviously look back at the old days when men sounded like men, phones sounded like phones and little furry creatures from alpha centauri sounded like little furry creatures from alpha centauri.
