This guys is sitting at the end of a bar. Each time someone comes in the door he says, rapidly,"Tickle your ass with a feather?" At which point they usually ask him what it was he said, and he then says, "Terribly nasty weather." They then go off looking confused. A drunk a few stools down observes this and finally says, "Say, buddy, I see what'cher doin'-- you're putting people on! When somebody comes in the door you say, Tickle your ass with a feather, and when they say, What did you say to me? you say, terribly nasty weather." So the guy says to the drunk, "Yeah, it's fun putting people on. Come on down here and you do the next one that comes in." The drunk moves down to the end of the bar. In a few moments a person enters, and he says to her: "Stick a feather up your ass? She said, ìexcuse me, what did you say?î He says, ìcan you believe this fucking weather?î
