The Union House

An accountant was at a convention in Las Vegas and decided to check out the local brothels. When he got to the first one, he asked the madame, "Is this a union house?"

"No, I'm sorry, it isn't." 

"Well, if I pay you $100, what cut do the girls get?" 

"The house gets $80 and the girls get $20." 

Mightily offended at such unfair dealings, the man stomped off down the street in search of a more equitable shop. 

His search continued as long as you want to draw things out, until finally he reached a brothel where the madame said, "Why yes, this is a union house."

"And if I pay you $100, what cut do the girls get?" 

"The girls get $80 and the house gets $20." 

"That's more like it!" the man said. He looked around the room and pointed to a stunningly attractive redhead. "I'd like her for the night." 

"I'm sure you would, sir," said the madame, gesturing to a fat fifty-year-old woman in the corner, "but Ethel here has seniority."
