Stop or My Dog Will Shoot (S18, E20-398)

The design flaw here is that now, Robodog can not literally take a bite out of crime.

Plot Summary
The Simpsons go to a Harvest Festival, but end up getting stuck in a massive cornfield maze.  For some reason, the family splits up, and eventually Marge and the kids escape.  Homer, though, is unable to get out and he remains stuck inside for hours.  The police arrive to help, but their retrieval dog has gotten old and has given birth to puppies, so that's no help.  Instead, Bart calls over Santa's Little Helper, who had been resting in the car, to come and help.  After picking up Homer's scent, the dog is able to locate and bring out Homer.  The police are impressed with the dog's effort and invite him to be a police dog.

After some brief training, Santa's Little Helper becomes part of the force, teaming up with Lou in the K-9 unit.  As Bart begins to miss his dog, Santa's Little Helper quickly becomes overwhelmed with his new life on the force, and begins to display a more aggressive attitude to stay in the game.  The dog is able to catch and apprehend Snake after he tried to sell illegal steroids, but after incorrectly filing the paperwork, the court is forced to let Snake go.  Lou lets the dog go home for awhile to cool off, but it does little good; as Bart comes from behind to greet his dog, the dog reacts aggressively and bites Bart in the leg.

After some discussion, its decided that the dog will stay with Lou.  Homer and Marge decide to get Bart a new pet, and Bart eventually decides on a Python he calls "Strangles".  Bart takes Strangles to school for show and tell, but the python slithers away, forcing the evacuation of the school.  The police arrive with its K-9 unit, but as they go in the python slithers into the science lab, unwittingly creating a toxic gas.  The police are forced to flee the school, but its learned that Bart is still inside, looking for Strangles.  Santa's Little Helper storms in to rescue Bart.  Bart does succumb to the gas, but is rescued by Strangles and/or the dog, and Bart decides to let the dog finish saving him.  The dog is freed of its responsibilities as police dog, reuniting him with Bart, while Strangles becomes Willie's new pet, though its new role at the school is something I'm not quite sure of.

Quick Review
This ended being a pretty weak episode.  Stephen Hawking makes a quick cameo during the dog's search in the cornfield maze, and it was appreciated, but there was hardly much else to like here.  Once the dog became part of the force, it was hard to find anything worth laughing, though the bit with Snake (Jailbird) was alright.  Strangles had its moments too, but it all still made for a less-than episode.

Final Score: 6.4
