When Stan Lee died on November 12, 2018 FOX rebroadcasted this episode with a "In Loving Memory" card at the end.
First appearance of Stan Lee as himself. He would go on to appear a few more times, usually in scenes involving Comic Book Guy.
Dan Castellaneta, the voice of Homer, voices the character voicing angry dad in his own regular voice.
When Homer watches When Dinosaurs Get Drunk and comments that he has been there when one sinks into the mud/tar, it may be a reference to the episode Bart Gets An Elephant, where he does the same in the sanctuary.
Homer sings a parody version of Donovan's "Mellow Yellow".
