"Do you know your way home from here by yourself?"
-An AJK twist on "I'm going to turn this car around if you don't stop", but with the clear indication that the party will keep going, without the offender.
A statement that always confused me to no end. Only recently did I determine what he was trying to say. (Hint: it's a little clearer if you make it "Blank 'em if they can't take a joke")
