In this episode of The Simpsons Theory, I tasked myself to tell you the past of every single Simpsons character from Matt Groening's The Simpsons. Who will they marry? How many kids will they have?

To do this, I watched every single Simpsons episode set in the past, as well as all of the flashback scenes in the show to bring you the most concise, and accurate, depiction of their life. So wanna see the pasts of Homer, Marge, Bart, Lisa and Superstar Maggie?
