Box Fort

Box Fort is a fort made from boxes by Bart and Lisa at their backyard.

History
Getting the idea from Ned, Bart and Lisa ordered many boxes for shipping from the A.S.S. (American Shipping Services) and Lisa decided to built a fort from them. When Raphael, who worked as a delivery man, learned it, he became angry and asked for them back. Lisa and Bart refused and Raphael threatens to come back and get them by force.

Later, he came back with an army of delivery men and women, with with a dragon, cardboard tubes and other cardboard weapons, and the fight began. It was a fierce battle and Nelson came with two cardboard tubes there to help Bart and Lisa. Finally, the A.S.S. army failed and fled.

Bart and Lisa then lost interest in their fort and melted it with the garden hose.

Behind the Laughter

 * The battle resembles the Battle of the Hornburd in J.R.R. Tolkien's The Two Towers.
