A union boss at a convention in Las Vegas decides to visit a brothel. He asks the madam, “Is this a union house?” “No, I’m sorry, it isn’t,” she says. “Well, if I pay $100, what do the girls get?” he asks. “The house gets $80 and the girl gets $20.” Offended by such unfair dealings, the man stomps off in search of a more equitable shop. Finally, he reaches a brothel where the madam says, “Why yes, this is a union house.” “And if I pay $100, what do the girls get?” he asks. “The girls get $80 and the house gets $20.” “That’s more like it!” the man says. He looks around the room and points to a gorgeous young redhead. “I’d like her for the night.” “I’m sure you would, sir,” says the madam, gesturing at a 70-year-old woman in the corner, “But Ethel here has seniority.”
