| Abandoned Lighthouse
| Location Information
The Abandoned Lighthouse is the place where Sideshow Bob retires.
After saving Homer and Grampa from the missile after having regrets, several years later, an elder Sideshow Bob is seen retired to a lighthouse to still go crazy over killing Bart, even after saving him, writing his message on the sand, just to be washed away by the water.
He's heard by the Squeaky-voiced teen, working as a mailman, delivers his mail. The Squeaky-voiced teen tells him he wouldn't disturb him for the mail and hear his rant if he gets a mailbox. Bob considers the option for good measure.
