I was walking through an alleyway, and this guy asks for change. I looked at him, decided he could use some cash and gave him a buck.  "Thanks," he said. "But what I really wanted, was to show you this funky wall."  He points to my right. Sure enough, it is a pretty funky wall: all bricks, red. Certain door shaped portions stand out from the rest of the wall, with huge leather straps running across them. The bum goes and knocks on one of them.  "Watch," he commands me. Soon, a tall, portly black man with a face like the Mayor's opens the door in a red smoking jacket. He is wearing red silk pyjamas underneath as well; you can see the fabric from his kees down to his feet.  "What the hell you want from me?" he asks the bum. "I don't have no gold pieces in here. No gold pieces. What you want? I told you I don't have no gold pieces in here!"  He shakes his head and slams the door in our face, Q.E.D.  Meantime, Jimmy comes out of a door somewhat to my right. Passing me, he thumbs over his shoulder:  "My sister's right in there."  I go into the hallway, follow it to the end, and see Lisa lying there on the bed, nude, back arched. I walk to the foot of the bed. "I find you very attractive," I say, very matter-of-factly. I put my hand between her legs. "Mind if I express that?" I ask in a scholar's tone. We make love.
