LOL!! Sam and Ruth are totally in cahoots over this. They plan a day and time and then make it look innocent. Ruth finally opens a window and says "Dean, sweetie, come over and get the key, I won't look." Then when Dean finally crosses the street in his polka-dot boxers and tries not to die and takes the key she's holding out the window, Sam unlocks the door. Then he insists that Dean can't get him back because it's just mean to pick on his blind brother like that, plus, does he really want to start that whole prank thing? Does he want to be called 'flower-boy' again around the shop?
