who plays mike's dad on mike and molly
List of Mike & Molly characters 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.
