Once they are assembled, the Simpsons sit down to Thanksgiving dinner. When Lisa places the centerpiece on the table, she fights with Bart about where it should go since there is no room left for the turkey. In the ensuing scuffle, Bart throws the centerpiece into the fireplace and it burns to ashes. Devastated, Lisa attacks Bart, but both Homer and Marge separate them and a heartbroken Lisa runs to her room crying. Angry with Bart for causing an incident during their Thanksgiving dinner, Marge and Homer send him up to his room. Marge then tells him that he has ruined Thanksgiving and later informs him that he will not be allowed to eat dinner until he issues a sincere apology to Lisa. Bart stubbornly refuses and insists the incident is Lisa's fault, not his.
