Mad Dogs and Average Men

S3, E18: Grace is smitten when she meets Sumner (guest star Paul Satterfield), the charming and handsome nephew of Karen (Megan Mullally), but Grace's attempts to arrange a date are constantly thwarted when Karen conjures up a litany of lies to dissuade her. Meanwhile, Will (Eric McCormack) tries to terminate his dead-end relationship with a needy nebbish (guest star Peter Jacobson) but postpones the dramatic moment because he's so infatuated with the guy's lovable doggie. Sean Hayes also stars.
