A dedicated Teamster was attending a convention in 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, it isn't she replied.
If I give you $100, how much does she get?
The house gets $60, the girl gets $40.
Offended at such an unfair deal, he stomped off in search of a more equitable, hopefully, a unionized shop.
Finally, he reached a brothel where the Madam said "yes, this is a union house"
He asked, "If I give you $100 how much does the girl get?"
The girl gets $80, the house gets $20.
"That's more like it," he said.
He handed the Madam $100, looked around and pointed to an attractive, blue-eyed blond, and said "I'd like her"
"I'm sure you would" she gestured to an 80 yr old woman and said, "Nancy here has 40 yrs seniority, and according to union rules, she's next".
