“There's a fine line between criminality and genius."
-Dan Cahill”

“There's a fine line between audacity and idiocy.”

“There is a thin line between genius and insanity. I have erased this line.”

“A lot of people say there's a fine line between genius and insanity. I don't think there's a fine line, I actually think there's a yawning gulf. You see some poor bugger scuffling up the road with balloons tied to his ears, he's not going home to invent a rocket, is he?”

“Its a fine line between love and stalking.”

“Sadly, there is a fine line between patriotism and paranoia.”

“It's a fine line between Saturday night and Sunday morning.”

“There's a fine line between a superpower and a chronic medical condition.”

“In this world, there is a fine line between enlightenment and brain damage.”

“The line between failure and success is so fine… that we are often on the line and do not know it.”
