The old man looked up at him and said, "Nope, never had a hankering to dance."
A crowd had gathered by then and the gunslinger said, "Well you old fool you're goanna dance now," and he started shooting at the old man's feet. The old man was hopping around and everybody was laughing. He fired his last bullet, holstered his gun and turned around to go back in the saloon.
The old man reached up on the mule, pulled his Sharps rifle out of the saddle scabbard, and eased the hammer back, making a loud click. The gunslinger heard this, then everything got quiet. He turned around and was looking down the end of a barrel that was bigger than a stovepipe aimed right at his stomach! The old man asked him, "Have you ever kissed a mules ass?"
The gunslinger swallowed hard, then said, "No, but I've always wanted to."
