We're on the Road to D'oh-where

We're on the Road to D'ohwhere is the eleventh episode of Season 17.

Plot
When Bart finds Principal Skinner's key to the steam tunnels while Skinner admires his new car, Bart and Milhouse fool around in the tunnels and open a steam valve, releasing a massive steam jet that explodes the school heaters, causes Groundskeeper Willie to burn his tongue when he tries to get a drink, rusts the band's instruments, causes frogs for dissection to come alive and attack the students, and generally rots the entire school. Skinner proposes that Bart be sent off to Upward Bound behavioral modification camp. Meanwhile, Moe announces that all of his frequent barflies will be going to Las Vegas, courtesy of him. Homer takes Bart to the airport to send him to the camp in northwest Oregon (preferably flying to Portland). But then he discovers that Bart is on the no-flight list and needs to be driven to the camp, thus excluding him from Moe's Vegas trip. After driving to a roadside diner, Bart escapes, and Homer nearly drives off a cliff.

Meanwhile, Marge and Lisa have a yard sale. It is a total flop until Otto discovers that Marge is also selling the family's expired prescription drugs. Marge makes lots of money selling prescription drugs and with a high price; later Chief Wiggum arrests her and puts her in jail.

The next scene shows Bart chained and ducted-taped to his seat complaining to Homer that he enjoys seeing his own son suffer. Homer then tells Bart that talking time is over and then putting tape over Bart's mouth. Bart sighs sadly. Homer gets Bart to the camp, but, after a moral dilemma, he decides to pick up Bart and take him to Vegas with him. In Vegas, Homer gets in a fight with a pit boss, loses track of Bart, and is thrown in Nevada State Prison. The episode ends with Lisa receiving phone messages from both her parents, asking for bail money. She sighs, telling Maggie that she will get a job tomorrow.
