Best lines in a song

There has been a long-running thread here of 'Best quotes' but maybe it would be interesting to find out folks' favorite lines from songs. To keep it on some sort of track, let's have a few ground rules.

- Attribution is required, who sang it (or wrote it) and where can we hear it?
- Shorter is better, four lines maximum, a verse. These should be words of wisdom that can be summoned for inspiration in social emergencies.
- If you're an opera fan, you're welcome to post in Italian, just don't expect many high fives from the monolingual among us.

Little Richard - Good Golly, Miss Molly

All I want in this life of mine is some good clean fun.
All I want in this life and time is some hit and run.
Little Feat - Fat Man in the Bathtub
Peter Gabriel -Biko

You can blow out a candle
But you can't blow out a fire
Once the flames begin to catch
The wind will blow it higher
Billy Joel-Only the Good Die Young

"I'd rather laugh with the sinners than cry with the saints"
Father, I want to kill you.

This is the end/ my only friend, the end.

Doors: The End

She left a lipstick letter on the mirror, shattered on the bathroom floor.
All I could put back together was '...never see me no more".

Delbert McClinton: When Rita Leaves
Welcome to truth custom made, come in and have some lemonade
Reality will re-adjust while we evade (77's - Ba Ba Ba Ba)
Professor Longhair - "Hey Now Baby"

Tell me pretty baby where did you stay last night
Tell me pretty baby where did you stay last night
When you come home this morning honey, your clothes didn't fit your right
