The New Adventures of Old Christine - Season 4 (2008)

Christine offers to marry Barb to help her stave off deportation. Meanwhile, Richard looks to pop the question to New Christine.

Richard begs Christine for the return of her old wedding ring which was an heirloom from his mother, in hopes of giving it to new Christine when he proposes.

Barb's profile in a business journal brings in new clientele.

Christine has been burning the candle at both ends -- working hard and trying to be a good mom. Ritchie decides he wants to join the reptile club at school and tells Christine all she needs to do is get the permission slip in on time. When Christine realizes that she's forgotten yet again, she asks the Reptile Guy (Jeffrey Tambor) to make an exception. He says the only way he'll consider is if Christine will go on a date with him. As creepy as he is, Christine is determined not to let Ritchie down, and so she complies.

Christine is distraught when Ritchie stops saying "I love you" to her. When she reveals her distress to Matthew, she also admits that she's been sleeping in Ritchie's room every night. Matthew tells her that if she's not careful, Ritchie will end up like him -- he can't go to sleep without talking to their mother. They spend the night helping each other break these habits.
