"Union Shops" joke
A dedicated shop steward 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 Bertha here has seniority!"
