of the population was drawn to resemble an ice pop. The Simpsons' staff had a lot of trouble finding a guest star for the second rocket, and the only person who agreed to participate was American actor Tom Arnold. In the episode, Arnold is depicted as an annoying, "not-so-great" celebrity. Although he was mostly in on the joke, Arnold did "bust [the staff's] chops" a little bit when recording his lines. "He would say a line and then they'd yell cut and he'd look over at me and take a shot at me" Hauge said. Still, Hauge found Arnold's performance "fantastic" and Scully said that he was a "good sport". The segment also features television personality Dick Clark as himself. A few months after the episode aired, Hauge discussed the segment with Clark in a Fox studio. According to Hauge, Clark said that the episode gave the "biggest response" he had ever gotten from anything he had ever done. "After the career that he had in television for so long, just to give him a highlight was a highlight for me" Hauge said in the episode's DVD commentary. Cultural references The opening segment, which shows Kang and Kodos attempting to entertain an audience of aliens, was "born out of [The Simpsons' staff's] love" of comedy teams like Martin and Lewis and the Smothers Brothers. The plot of "I Know What You Diddily-Iddily-Did" is based on the 1997 horror film I Know What You Did Last Summer. At the beginning of the segment, the Simpsons are seen escaping from a group of vampires. Holding a package of Super Sugar Crisp cereal, Homer starts singing a jingle about the cereal. Super Sugar Crisp is a reference to the breakfast cereal Golden Crisp, while the jingle Homer sings references "Can't get enough of that Golden Crisp", a jingle sung by Golden Crisp's mascot Sugar Bear during advertisements for the cereal. According to Scully, the series' staff had a lot of trouble clearing the song for the episode. "Apparently, they didn't want the tune [...] used in this context" he said in the episode's DVD commentary. Although there is a Marvel Comics character called Collector, Long did not base The Collector on him. While carrying Lawless with an electromagnet, The Collector says "Care for a Rolo, sweet Xena?" The reference was included because the writing staff were given free Rolos at the time. In
