that he was in fact in Marge's body Bart Swapped Bodies with Mom and Showed Off in a Bikini

Bart had been playing video games at home one afternoon when he realized he had the power to make his dreams come true. He thought to himself, "If I could switch bodies with my mom, Marge, I'd be able to show off in a bikini to everyone in school!" So he closed his eyes and focused all his energy on his desire to switch bodies. When Bart opened his eyes, he was shocked to discover he was in Marge's body! He quickly realized that the switch must be permanent, and Marge was now stuck in his body. But Bart was determined to make the most of his new body, so he put on a bikini and headed off to school. When he arrived, everyone was shocked to see Bart in Marge's body. Some even laughed at the sight! Bart laughed too, and posed for pictures in his new body, reveling in the attention he was getting. As the days passed, Bart enjoyed his newfound freedom in Marge's body. He took baths every day, with the intention of letting everyone see that he was in Marge's body. Eventually, people started to realize that Bart was in Marge's body and the swap was permanent. They accepted the situation, and eventually, Marge settled in to her new life in Bart's body. Though the swap was permanent, it taught everyone an important lesson: no matter how different we may look, we all have the same feelings and desires on the inside.
