"Ol' Blue Nose" is the 1st episode of Season 5 of the show.
Ren hits Stimpy in the nose (after he spends the last quarter they had on the bus station tv) and he starts to sing with a Frank Sinatra-like voice. Stimpy becomes famous, until his nose leaves for a solo career over creative differences.
- 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)
- Stimpy's song is an obvious reference to Frank Sinatra's hit song, "Come Fly With Me".
- This is the only episode written by Billy West.
