Frasier and Niles heed Marty's advice and throw a singles party (although I don't know where all these people came from). The figure there will be at least one woman for each of them. Complications occur, especially involving Martin's hair. Also, Roz is there and she is really in the final stages of pregnancy. Nile and Frasier go into full confrontation mode. But Roz has her water break which leads to some ugliness in the waiting room.
