A mountain man-type guy comes down out of the hills to cash in the gold he has panned.
He wants a little piece of action.
After getting his money, he heads straight to the closest whore house.
Inside he says to the Madam, "Send me up a bottle of beer, a box of matches and the roughest, toughest whore that you got. I'm awful horny and I want a woman who can handle me."
Fifteen minutes later, there is a knock at the door to his room and in walks a pretty young girl with a box of matches and a bottle of beer.
"If you don't mind," said the mountain man. "I'd like to administer a little test to make sure you're rough and tough enough. Drop your knickers and bend over."
She does as she's told and he takes one of the matches out of the box and attempts to strike it on her bare ass.
It doesn't light, so he tells her to get out and to tell the Madam to send up a real rough and tough whore.
This scene is carried out repeatedly until the Madam discovers that she has run out of whores.
Knowing that she must make the customer happy, she goes up herself to satisfy the mountain man.
Like the others, she drops drawers and bends over when she is told.
He rakes the match across her ass and it bursts into flames.
"Now, that's more like it!" says the mountain man happily.
Then he notices that the Madam is still bending over. "You can stand up now," he says.
"But," says the madam, "don't you want to open the beer?"
