Kramer meets him in the sauna at the health club. Kramer believes that Sal Bass is really Salman Rushdie and tries to get information out of him to prove it.
KRAMER: Jerry, are you blind? He's a writer. He said his name was Sal Bass. Bass, Jerry! Instead of salmon, he went with bass! He just substituted one fish for another!
JERRY: Look, you idiot, first of all, it's Salman, not salmon!
