The opening refrences the fact that due to the Fox network's coverage of the World Series (which one game usually falls on Sunday), the Simpsons halloween show is pushed to november.
Kang and Kodos wonder if speeding up time will allow the Chicago Cubs to win the World Series, a reference to the team's long-standing championship drought. In 2016, they won the World Series for the first time in 108 years. Coincidentally, this episode aired less than two weeks after the Chicago White Sox, the Cubs' crosstown rivals, ended their World Series title drought of 88 years.
At the end of the segment, Maggie the witch flies up to the moon, accompanied by the theme music of Bewitched, in a scene very similar to the TV series' title animation.
Tress MacNeille voices the witch in this segment, who also voiced the Wicked Witch of the West in the animated Wizard of Oz show from the 90s.
The show Pomona on the opening sequence from FOX references the real life city of Pomona, California, which is located in Los Angeles County in the Pomona Valley with a population of 149,058 as of the 2010 United States census. "Pomona is hotter away from the beach" is said in the announcing of the new show at the game, because Pomona is thirty miles away from the nearest beach.
"I've Grown a Costume on Your Face" is similar to an issue of Simpsons Comics' Bartman, in which Itchy and Scratchy are brought to life through alien technology create a nuclear explosion which turns the Simpsons into costumed superheroes.
Kent Brockman: Flung from a tree, and was the last person to be shot out of the air.
Moe Szyslak: He was flung from the tree along with the others, but Burns missed him. After taunting Burns, he ironically lands on on a weather vane, impaling himself. He still survives, wins the lottery, and is about to leave to cash it in, but Chief Wiggum lands on him, crushing and finally killing him.
Clancy Wiggum: Falls on a weathervane and dies instantly, crushing Moe.
Professor Frink: Eaten by Homer, who passes up bananas, saying that they look green.
Sideshow Mel: Shot by Burns, using machine guns on a plane during a strafing run.
Hank Azaria is credited as "No Seriously, The Republican Party", which is somewhat odd as his real name or a variant of it does not appear in the "name" at all.
When Homer, Carl, and Lenny were in the first shot, the plaques that Mr. Burns would hang their heads on are missing but after Barney says "The most dangerous game, I wonder what it could be?" The plaques suddenly appear over Lenny and Carl.
