The Gunslinger

An old prospector walks his tired old mule into a western town one day.He'd been out in the desert for about six months without a drop of whisky. He walked up to the first saloon he came to and tied his old mule to the hitch rail.

As he stood there brushing some of the dust from his face and clothes, a gunslinger walked out of the saloon with a gun in one hand and a bottle of whisky in the other.
The gunslinger looked at the old man and laughed, saying, "Hey, old man, have you ever danced?"
The old man looked up at the gunslinger and said, "No, I never did dance. I just never wanted to."
A small crowd had gathered by then and the gunslinger said, "Well, you old fool! You're gonna dance now," and started shooting near the old man's feet. The old prospector just stood there, never moved and everybody was laughing.
When the gunslinger fired his last bullet, he holstered his gun and turned around to go back into the saloon.
The old man reached up on the mule, drew his shotgun and pulled both hammers back making a double clicking sound. The gunslinger heard the sound and everything got quiet. The crowd watched as the gunslinger slowly turned around looking down both barrels of the shotgun.The old man asked, "Did you ever kiss a mule square on the ass?"
The gunslinger swallowed hard and said, "No. But I've always wanted to."
