This is a really hard one but, mine has got to be "The sky is full of dreams.....but you don't know how to fly, I don't have a simple answer...but I know that I can answer" from This Is Your Life. It has a lot of truth to it.
"Acid rain, when Abel looked up at Cain. We began the weeping and wailing. A huried high of pestilence, pills and pride. It's a shame, we could've gone sailing."
