Butch: "Just ask us to stay"
"Could you stay?"
Butch:" no we got to go"
"I've got vision and the rest of the world is wearing bifocals"
Very last scene... they're holed up, getting ready to make one last escape:
Butch: "When we get outside, when we get to the horses, just remember one thing. Hey, wait a minute."
Sundance: "What?"
Butch: "You didn't see Lefors out there, did ya?"
Sundance; "Lefors? No."
Butch (confidently): "Good. For a moment there, I thought we were in trouble."
