Old Dave 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 old mule to the hitching 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 whiskey in the other. The gunslinger looked at Old Dave and laughed, saying, "Hey old man, have you ever danced?"
Old Dave 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 you old fool, you're gonna' dance now," and started shooting at Old Dave'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. Old Dave 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.
Old Dave asked, "Did you ever kiss a mule square on the ass?"
The gunslinger swallowed hard and said, "No. But I've always wanted to."
Don't mess with old farts named Dave. . . . .
