- The episode title is a reference to the comedian Art Carny.
- A deleted scene from this episode shows Principal Skinner and his mother visiting the ring toss booth while Homer and Bart run it. This scene, however, is included in the original broadcast.
- When Marge asks how the Athena was able to sink, it cuts away to a shark ramming the glass causing fractures not unlike the one that doomed the Athena, with Bart and Homer taunting it (by mooning and jiggling the gut, respectively), implying that the Athena sunk because rowdy tourists started taunting some of the wildlife. The scene of the shark attacking the boat is also similar to a scene in Jaws.
