Given the task definition and input, reply with output. In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: Gigolos in Europe are being terrorized by a serial killer. In Malibu, Deuce Bigalow's wife Kate has died from a shark attack, and Deuce is invited by his former pimp T.J. Hicks to Amsterdam. Deuce goes to take his mind off of Kate.
After T.J. shows Deuce his boat, or "float crib," the pair go to a coffee shop where they get high and bump into Heinz Hummer, a German gigolo. After leaving the coffee shop, Deuce finds Hummer dead in an alley, but thinks he is merely stoned and takes the dead gigolo to T.J.'s float crib; when T.J. gets back, he immediately realizes that Hummer is dead. T.J. plans to dump the body, but skeptical of Hummer's reputation of being well-endowed, unzips his pants and examines his genitalia and is caught by a tour boat.
Upon his release from the police station, Deuce finds T.J. at a restaurant and recalls that he saw the killer walking away from Hummer's body. Deuce says it was a woman, so they both figure it was a she-john, a former client of the murdered gigolo. T.J. convinces Deuce to find the killer by becoming a gigolo again, visiting the former clients and "rooting" out the killer. They attend a meeting of the Royal Order of European Man Whores, but fail to procure a list of the clients.
What are the full names of the characters who go to the meeting of the Royal Order of European Man Whores?
