Mothers-in-law don't always have the best reputation. Many mother-in-law relationships are notoriously difficult, such as Ralph Kramden's relationship with his own mother-in-law on "The Honeymooners": -- hates me, Alice! Lucky for me, my mother-in-law doesn't hate me. And I don't hate her. We get along just great.
