A KRFF Hearst College radio show, hosted by the one and only Mercer Hayes. You have to admit, the name of his program upholds the same standards of base humor as Cap'n Krunk and Imitation Crab. However, while those pirate radio DJs were molested and nicknamed after a South Park character respectively, Mercer is only the owner of an illegal gambling establishment, the Benetian. He is suspected of being the Hearst rapist, though. We don't learn much about Flush in 3.01 "Welcome Wagon," but we learn more than enough in 3.06 "Hi, Infidelity."
