"A Millionaire Matchmaker 'mixer' will look familiar to anyone who has seen Cathouse, the HBO reality show about a legal Nevada brothel. A recurring Cathouse motif-it's featured in the show's intro-is the "lineup," when new clients enter the Bunny Ranch and all available prostitutes come rushing from their rooms so that the potential buyer can inspect the merchandise. 'Girls, come and meet my millionaires,' Patti cries, and whatever cavernous LA-cheesy venue she's selected becomes an ad hoc brothel."
