Kinda hijacking a thread idea here. But what's your absolute favorite line from a song?

"All you savage cats know that I was strapped with gats when you were cuddlin' a cabbage patch"
Not my number one but that might be the best from any rap song ever 
Way too many, but this is the first one that popped into my head.
Ray LaMontagne - Empty
Well, I looked my demons in the eyes
laid bare my chest, said "Do your best to destroy me.
You see, I've been to hell and back so many times,
I must admit you kind of bore me."
Just remembered another one.
Goldenrod and the 4h stone.
The things I brought you when I found out you had cancer of the bone
Casimir Pulaski Day by Sufjan Stevens
That line let's you know you're about to listen to a depressing song. Haha.
'Maybe I will never be all the things that I wanna be, now is not the time to cry now's the time to find out why.'
Oasis- Live Forever
Love that fucking line.
Technical Primates -
'Maybe I will never be all the things that I wanna be, now is not the time to cry now's the time to find out why.'
Oasis- Live Forever
Love that fucking line.
The sun's not yellow, it's chicken.
Bob Dylan - tombstone blues
I didn't realize we were going with more serious stuff. In that case I'll amend my answer.
"Everywhere I look, you're all I see
Just a fading fucking reminder of who I used to be"
Let's not forget this one
"I am the egg man, they are the eggmen. I am the walrus, goo goo g'joob."
"Now your up shits creek, with a turd for a paddle." - piss up a rope, by Ween.
Fuck it all! Fuck this world!
Fuck everything that you stand for!
Don't belong! Don't exist!
Don't give a shit!
Don't ever judge me!
Surfacing - Slipknot
Van Morrison's Wild Night
"All the girls walk by, dressed up for each other"
If only we could heal ourselves, we wouldn't need to be hooked up to these machines
Say it will always be like this
the two of us together
it will always be like this
forever and ever and ever
Tough one
Termination...expiration...cancellation...human race!!! See our mother put to death....see our mother die!!!
Hell is not a place you go if your not a christian its the failure of your lifes greatest ambition
When I come home
Late at night
Don't ask me where I've been
Just count your stars I'm home again
Do you miss the blend
of colors she left in your black and white field?
Do you feel condemned,
Just being there?
Sowing Season - Brand New
"Sometimes I claim to know a guy but I can't even tell you what his hands look like"
Why? - Alopecia
That entire album is filled with amazing lyrics. It's hard to pick my favorite line but this one always stuck out.
