The Manager of the Philadelphia Victorian Hotel looks exactly like Eric, and thinks like him too. Eric convinced him that he is E.J. Peterman, the rich owner of a disposible diaper empire, and moves the planned Peterman wedding up so Cory and Topanga can get married instead. He speaks with an Eastern European accent.
When the real Mr. Peterman shows up, he and the manager get into an enormous fight. Even though Mr. Peterman is furious, the manager holds his own. He yells very loudly in a very high pitched voice.
