Magische Weihnachten - A Very Nutty Christmas

Kate tells Chip that her cookies and brownies are named after family members. The first one is the Sabrina Snickerdoodle, an obvious reference for the Melissa Joan Hart fans, to her character in "Sabrina, the Teenage Witch". The other names are Joe, Aviana, Bella, Clover, Dizzy Izzie, Oliver and Paula. She says Aviana is her niece, which is true - Melissa really has a niece named Aviana. The name Paula is clearly a reference to Melissa's mother Paula Hart.

When arriving at the theater, Kate is being repeatedly shushed by the audience while she's yelling at Chip, and she finally shushes the audience right back; at that moment an extra right behind her--a blonde lady wearing a pearl necklace--can't help herself but grin broadly and sweetly at Melissa, thereby breaking character: she, (along with the rest of the audience) is supposed to be very upset at Kate for yelling so much and disrupting the peace, but we can tell from that lady's sweet smile and tender look at the actress, that she was amused by how well Melissa performed her aggravation in that scene. This goof turned into a very cute moment.

At the beginning of the closing credits we see a closeup of the nutcracker winking it's right eye.
