An old prospector had been out in the desert for about six months without a drop of whiskey. He walked up to the first saloon he came to and tied his mule to the hitch rail. As he stood there, brushing some of the dust from his face and clothes, a young gunslinger walked out of the saloon with a gun in one hand and a bottle of whiskey in the other.
The young 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 crowd had gathered by then and the gunslinger said, "Well, old fool, you're gonna dance now," and started shooting at the man's feet.
The old prospector was hopping around and everybody was laughing. When the gunslinger fired his last bullet, he holstered his gun and turned around to go back into the saloon.
Just then, 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 every kiss a mule's a__?
The gunslinger swallowed hard and said, "No. But I've always wanted to."
