Terribly Nasty Weather

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:

- Excuse me, what did you say?

He says:

- Can you believe this fucking weather?
