Even though Felix had just repainted the living room ('flaming peach' Oscar: what colour was it before? Felix: Spanish mildew) in the previous episode (Take My Furniture, Please (1973), the apartment's back to 'Spanish mildew'.
A shot from this episode (after Felix sends Murray off to work, and Oscar refers to Murray as 'blubber in blue') - Oscar angrily telling Felix, 'he goes out', is incorporated into the next season's opening credits
In the previous episode, Felix sells all of the furniture and buys new furniture; however, in this episode, the original furniture has reappeared.
The scene of Oscar & Felix jogging, where Oscar calls a cab was reused from an earlier episode, although with different dialogue dubbed over it.
Jane Dulo portrays Murray's wife having portrayed Oscar's mother earlier in the season (The Odd Couples (1972)).
