A dedicated Teamsters union worker was attending a convention in Las Vegas and decided to check out the local brothels.
When he got to the first one, he asked the Madam, "Is this a union house?"

"No," she replied, "I'm sorry it isn't."

"Well, if I pay you $500, what cut do the girls get?"

"The house gets $300 and the girls get $200," she answered.

Offended at such unfair dealings, the union man stomped off down the street in search of a more equitable, hopefully unionized shop. His search continued until finally he reached a brothel where the Madam responded, "Why yes sir, this is a union house. We observe all union rules."

The man asked, "And, if I pay you $500, what cut do the girls get?"
"The girls get $350 and the house gets $150."

"That's more like it!" the union man said. He handed the Madam $500, looked around the room, and pointed to a stunningly attractive green-eyed blonde.
"I'd like her," he said.

"I'm sure you would, sir," said the Madam. Then she gestured to a 92-year old woman in the corner, "but Ethel here has 67 years seniority and according to union rules, she's next."
