Cover art for Under The Gun lyrics by Sisters of Mercy, The

"Happiness is a loaded weapon and a Short cut is better by far Explosive bolts, ten thousand volts At a million miles an hour"

"I put my finger on and fired Heat-seeking, out of the sun You can set the controls for the heart or the knees And the meek'll inherit what they damn well please"

go figure..
