An old prospector finds a gold nugget...

Excited to have a little cash and looking to celebrate, he gets on his donkey and rides it down into town. He walks into the saloon, has some whisky, and then says, "Bartender, you got any women around here?" The bartender says, "Nope. But we got old Fred in the back." The prospector looks disgusted and says, "Nope, nope, nope. I don't go for that shit." gets back on his donkey, and rides back to his mine.

A few years later, he finds another nugget. Once again, he rides into town on his donkey, drinks a whisky, and says to the bartender, "Bartender, you get any women around this place yet?" The bartender shakes his head and says, "Nope. But we still got old Fred in the back." As before, the prospector is disgusted and says, "Nope, nope, nope, I don't go for that shit." before getting back on his donkey, and riding back up into the hills to his mine.

More years pass, and now the prospector is getting old and approaching the end of his life. He finds another nugget, and rides down into town. He orders a whisky, and in a desperate, pleading, voice says, "Bartender, you must have some women around here by now, right? I've been forty years now without the comfort of a woman." The bartender shakes his head sadly and says, "Nope. Sorry. Still got old Fred in the back though, if you're interested." The prospector mulls it over, leans in and whispers, "Bartender, if I do it with old Fred, who will know?" The bartender replies, "Well...you. Me. Old Fred, of course. And the three guys holding old Fred down. He don't go for that shit either."
