This episode features three members of the DeLuise family: Michael DeLuise reappears in his guest role as Luke's sister's boyfriend TJ; his brother David DeLuise plays TJ's brother; and their father Dom DeLuise is briefly visible on TV as Rory and Lorelai watched his movie Fatso (1980).
The scenes where Rory and Paris visit Asher Fleming in hospital were filmed on the set of ER (1994).
Rory mentions that Paris could be hit on the head by an anvil at any time - this references a rant Lorelei had about anvils at Friday night dinner in a prior episode this season
In previous episodes it has been mentioned that Jackson has sang to the persimmons and danced with the watermelons so her being confused by him sleeping with the zucchini's seems odd.
When Luke locks the door after Jess leaves his apartment, he turns the lock then waits a second for the locking sound effect to play.
