Almost exactly two years earlier Jerry was being picked on and said he did not care because he was only two years from retirement and free from all of this.
The breakfast nook in Jerry/Gary's kitchen is the same as Ben's sister's kitchen when they visit Partridge in Partridge (2013).
Jerry actually qualified for a government pension some 30 years ago. It is revealed in this episode he worked in the parks department for 40 years. In Indiana, one vests in a public pension after ten total years of service. Therefore, not only has Jerry been eligible for a pension for 3 decades, it was also false when he said two years ago that he still needed two years to qualify.
On Ben's day off, he wears a Letters to Cleo t-shirt. Letters to Cleo is an early 90's alt-rock band. They broke up in 2000 but did a reunion tour in 2008. In 2016, Letters to Cleo announced they were in the studio recording again.
