The episode marks the first appearance of recurring guest star Albert Brooks. In this episode, and all of his subsequent appearances he is credited as A. Brooks.
Flanders makes $27 more a week than Homer does (although this is based on Ned's original job at a pharmaceutical company, not the Leftorium). This would mean as a pharmacologist Ned Flanders made $1,404 a year greater than Homer's salary, although Ned makes far better use of his credit.
Signs at Bob's RV-Roundup (formerly RVs R Us): "We want to make friends :-) Not Profit :-(" "We give credit to everyone!"; "Bad Credit. Good!"; "Bankruptcy Shmankruptcy."
The Ultimate Behemoth RV: two-stories high with a fireplace, a full kitchen, four deep fryers---"one for each part of the chicken," a big-screen television set, and its own satellite, the Vanstar I.
For all its great status as a "castle on wheels", Ned's Land Behemoth RV is not seen again. Presumably Ned sold the Land Behemoth in order to raise capital to acquire the Leftorium.
A much later episode does make reference to Ned still owning the RV. When trying to come up with a way to raise money for the church he mentions that he has an RV he never uses that they could sell.
When Maggie watches Homer and Bart running away in terror, her bow on her hair was missing.
As Homer notices that his clothes are gone, a branch is covering him, however it wasn't there before when he swam to shore.
When Lisa reminds Homer, her shirt is green. It is normally purple.
Lisa tells Homer that the handle of the Big Dipper points to the North Star. This is incorrect. The handle points to Arcturus, "Follow the Arc to Arcturus". Instead it is the two stars which make the "front" of the Dipper's "cup" point to the Polaris.
