Loved Mysterio's line : "It's easy to fool people when they're already fooling themselves"
Also : Thanos and evil Nebula:
"They'll never see us coming"
The arrogant never do".
Non comics?
Maybe - Kris Kristofferson in Payback - "don't Sh** where you sleep. ...No don't sh** where you live. I like that better"
Predator 2 : "I tell you what I believe .. Sh** 'appens"
Cyrus the Virus pointing gun to Pilot's head : (We'll crash!) "I don't think that far ahead"
