The fourth Simpson child,
20 February 2011 | by (Ireland) – See all my reviews

O Brother where Bart thou is a great Simpsons episode featuring the fourth Simpson child (nectically not).

After Bart gets jealous of great bonding Lisa and Maggie share,Lisa says that he will never no what its like since he doesn't have a brother.After that Bart goes through everything he can to get Homer to get Marge pregnant,romantic dinners,putting erotic dvds under neat their pillow,changing Marges pills.

After none of it works Bart goes to an orphanage and adopts a little brother,but he begins to learn its a lot more responsible than he thought.
