Bart vs. Thanksgiving is the Thanksgiving episode of The Simpsons. It was part of the second season and first aired on November 22, 1990.
It is Thanksgiving and Lisa assembles a decorative centerpiece for the dinner table. The Simpson family sits down to give thanks along with Grampa, Patty, Selma, and Marge's mother. When Lisa places the centerpiece on the table, she argues with Bart about where it should go since there is no room left for the turkey. In the ensuing fight, Bart accidentally throws the centerpiece into the fireplace and it burns up. Devastated, Lisa runs to her room in tears, while Bart is sent to his room by Homer and Marge for ruining Thanksgiving.
Convinced he has not done anything wrong, Bart decides to run away from home, taking Santa's Little Helper with him. Walking the streets alone, cold, and hungry, he visits a soup kitchen that is serving Thanksgiving dinner for homeless people. A television crew led by Kent Brockman is covering the event, and they interview Bart on live television. The family sees the report and calls the police. Homer and Marge start to regret the bad things they said to Bart. Bart eventually returns home feeling remorseful. However, the situation is worsened when he imagines that the family does not forgive him and makes everything his fault. He climbs up onto the roof of the house to think things out. Hearing Lisa cry because she misses him, Bart calls for her to come onto the roof. He realizes that what he did was wrong and apologizes to her. Bart rejoins the family to enjoy a meal of Thanksgiving leftovers later that night.
