Santa's Little Helper becomes a police dog while Bart gets a pet snake.
- Deleted Scene: There was supposed to be an appearance by former New York City mayor Rudolph Giuliani (voiced by the man himself) in the original version of this episode, but it was cut for time. The cut scene can now be seen in syndication and (hopefully) will be put on the season 18 DVD if and when it gets released.
- Schedule Slip: Originally, this was supposed to air in April, but it had to be pulled due to the Virginia Tech shootings (the episode included irresponsible gun use and the school evacuating due to an emergency).
- Shout-Out: The episode's title is a reference to Stop! Or My Mom Will Shoot.
