At the time this episode first aired, Tugboat Granny (1956) and Barney's Hungry Cousin (1953) had not yet been released by Warner Bros. on DVD or Blu-ray, though "Tugboat Granny" was available in a restored print on the HBO Max streaming service.
Boston Billy wants to see more Toe-ny the Toe-na (the red sock character), not Bill the Cotton Curator (the white sock character). This is a reference to the Boston Red Sox baseball team, as well as the Chicago White Sox baseball team (the latter of which is understandably less popular with a Bostonian like Billy).
A Witch's Tangled Hare (1959) had been featured previously in Stuff & Nonsense #4 (2021), and The Dog House (1952) had been featured previously in Bill and Toony's Bad Luck (2021).
When Bill's Mom takes Sockeye Sam to the International Bucket Museum, she mentions seeing a woman with a bucket over her head, a reference to the character Ms. Bucket Head, introduced in Can of Cake! (2021).
Guest characters include Bill's Mom, Sockeye Sam ("Somewhat Intelligent Sock"), Sue P. ("Sales"), and Boston Billy ("Wicked Awesome", making his first appearance). The sock puppet versions of Toony, Bill, and Sue P. are named Toe-ny the Toe-na, Bill the Cotton Curator, and Shoe P., respectively.
