Cooper: "Hey TARS, what's your honesty parameter?"
TARS: "90 percent."
Cooper: "90 percent?"
TARS: "Absolute honesty isn't always the most diplomatic nor the safest form of communication with emotional beings."
Cooper: "Okay, 90 percent it is."

TARS: "Honesty, new setting: ninety-five percent."
TARS: "Confirmed. Additional settings."
Cooper: "Humor, seventy-five percent."
TARS: "Confirmed. Self destruct sequence in T minus 10, 9..."
Cooper: "Let's make that sixty percent."
TARS: "Sixty percent, confirmed. Knock knock."
Cooper: "You want fifty-five?"

"Everybody good? Plenty of slaves for my robot colony?"

TARS: "I have a cue light I can use to show you when I'm joking, if you like."
Cooper: "That might help."
TARS: "Yeah, you can use it to find your way back to the ship after I blow you out the airlock. [cue light flashes]"

Cooper: "What happens if he blows the airlock?"
TARS: "Nothing good..."

Cooper: "Detach!"
Brand: "Goodbye TARS."
TARS: "Good-bye Dr. Brand. See you on the other side Coop."
Cooper: "See you there slick!"

Cooper: "What's your trust setting, TARS?"
TARS: "Lower than yours, apparently."
