- This is the first Season 5 episode.
- Despite being the first episode in Season 5, this episode and Stupid Sidekick Union aired two weeks before the final episodes in Season 4 (Superstitious Stimpy and Travelogue)
- Ren and Stimpy's song, "Come Fry With Me," is an obvious parody of Frank Sinatra's big hit song, "Come Fly With Me".
- This is the only episode written by Billy West.
