"Remarry?" joke

One night, a husband and wife were having a conversation over dinner: Wife: What would you do if I died? Would you get married again?
Husband: Definitely not!
Wife: Why not - don't you like being married?
Husband: Of course I do.
Wife: Then why wouldn't you remarry?
Husband: Okay, I'd get married again.
Wife: You would? (with a hurtful look on her face)
Husband: (makes audible groan)
Wife: Would you sleep with her in our bed?
Husband: Where else would we sleep?
Wife: Would you put away my pictures, and replace them with pictures of her?
Husband: That would seem like the proper thing to do.
Wife: And would you let her use my golf clubs?
Husband: She can't use them; she's left-handed.
Wife: - - - silence - - -
Husband: shit.shit.shit...
