1x9 - The New Adventures of Old Christine

Christine tries not to have a meltdown when her ex-husband, Richard, brings his "new" Christine with him to pick up Ritchie and take him to breakfast so that they can get to know one another. By day's end, Christine tries to pull herself together to make a good impression at parents' night at Ritchie's school, but is caught off guard when "new" Christine shows up as well.
