After the episode aired, the staff received a letter from a Vietnam veteran who was angry about the Vietnam flashback scene. Incidentally, Matt Groening's brother, himself a Vietnam veteran, loved the sequence.
Ralph is stated to be Police Chief Clancy's son for the first time here, confirming what everyone had suspected since the revelation in Kamp Krusty (1992) that they share the surname Wiggum.
In the clip of Krusty's show with Robert Frost, Frost is reading from his poem, "Stopping By Woods On A Snowy Evening." After Krusty dumps fake snow on his head, his line, "We discussed this and I said no!" is spoken in the same meter as the poem.
The scene of Chief Wiggum sitting behind Krusty at an adult movie theater and Krusty thinking he is about to be arrested is a reference to Paul Reubens' arrest for masturbating at a pornographic movie theater in Sarasota, Florida.
When Ralph tells Lisa, "Leave me alone, I'm here to play George Washington." He sits down in a wheelchair, dons glasses, and smokes a cigarette- a reference to former president Franklin Roosevelt.
