Karen Bender (née Simonds, previously McCluskey) was Wisteria Lane's local babysitter who loves to cause trouble, who was originally introduced as Lynette Scavo 's nemesis. She is mainly referred to as Mrs. McCluskey. As the series went on, Karen became humanized and even became a friend to the women.

After her husband died, she hid his body in her basement freezer in order to keep collecting his pension checks. Right before he died, Karen discovered Gilbert had a lover during the course of their marriage, and decided to keep his checks as retaliation and revenge.

To thank Lynette for saving her life, Mrs. McCluskey presents her with a Tiffany lamp. But it comes with strings attached - now she wants to come over to chat and to tag along on Lynette's errands. Lynette responds by handing back the lamp. The next day, Lynette signs for a package for Mrs. McCluskey when she doesn't answer the door.
