Frasier's dad Martin (John Mahoney) is an eligible widower. Roz's mom Joanna (Eva Marie Saint) is likewise unattached. Frasier (Kelsey Grammer) and Roz (Peri Gilpin) are thus convinced that the union between Martin and Joanna would be the proverbial "match made in Heaven." The results: Joanna is exultant -- and Martin is annoyed. And speaking of matchups, listen for the Very Famous Couple providing "guest voices" during Frasier's radio call-in show. ~ Hal Erickson, Rovi
