I remember a great radio ad I heard during my commute about 20 years ago, which was an alternating series of playing answering machine messages between a couple where he proposed, she accepted, discuss pre-nup and faxing to each other, etc. It was VERY amusing. I can't do it justice here, but suffice it to say that it's the only radio ad I still enjoy remembering almost 20 years later--that should say something about how good it was.
