<P> Jack Biggs ( Francis Guinan ) is Mike 's father , who left Mike and his mother many years ago to run off with a woman whom Peggy simply refers to as `` the whore . '' He first appears at Mike 's bachelor party in Season 2 and tearfully apologizes to his son for running away , to which Mike honestly tells his father he loves him and is glad he will be at the wedding . After Peggy and he sleep together , he decides he wants to reconcile with her ( his marriage to `` the whore '' is rapidly disintegrating ) but Peggy bluntly says she only used him for sex and has zero interest in him now that he 's served his purpose . </P>
