For those who don’t know the story behind this:
Before Maggie was born, Homer worked at the Nuclear Plant because he needed the money to pay for all the debt. Once Homer finally payed the debt, he quit his job to work at his dream job at the bowling alley. When he found out that Marge was pregnant with Maggie, he became depressed that he had to quit his job at the bowling alley because the salary couldn’t support them. He begged Mr. Burns for his old life back and put a plaque that reads “Don’t Forget: You’re Here Forever.” When Maggie was born, Homer instantly fell in love with her. When Lisa asked him where all of Maggie’s baby pictures went, he explains that he keeps them where he needs them the most.
