Main Characters in this Episode
- Goof (continuity error): When Bobby and Cindy are playing checkers, Oliver is shown wearing a Cal. State Northridge t-shirt. But just before Arthur comes in, the words on his t-shirt are shown covered up with tape which matches the stripes on the sleeves.
- Christopher Knight appears in a dual role.
- The title comes from the common expression: Just like two peas in a pod.
- This is the first filmed episode featuring Cousin Oliver, Carol's 8-year-old nephew. His appearance in the show is widely considered by fans as the moment when the series "jumped the shark" (that is, irrecoverably went into declining quality).
