Pink Floyd "Animals"
Dogs
"You got to be crazy, you gotta have a real need
You gotta sleep on your toes and when you're on the street
You got to be able to pick out the easy meat with your eyes closed
And then moving in silently, down wind and out of sight
You got to strike when the moment is right without thinking
And after a while, you can work on points for style
Like the club tie, and the firm handshake
A certain look in the eye and an easy smile
You have to be trusted by the people that you lie to
So that when they turn their backs on you
You'll get the chance to put the knife in"
