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 $100, what cut do the girls get?”  “The house gets $80 and the girls get $20” 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 $100, what cut do the girls get?”  “The girls get $80 and the house gets $20.”  “That’s more like it” the union man says.

He handed the Madam $100, looked around the room, and pointed to a stunningly attractive 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 Mabel here has 67 years seniority and according to union rules, she’s next.”

That sure backfired.
