Acceptable Targets: Special education (though this might be considered a Once Acceptable Target, as some Moral Guardians will protest over how mental illness and mental retardation are depicted in TV shows and movies). That said, a few former special ed students have said that the depiction isn't too far off from reality, but they're few and far between.
Hilarious in Hindsight: At the time of this episode, the Denver Broncos were one of the worst teams in the NFL (hence Homer's disappointment in becoming their owner), while the Dallas Cowboys had won three out of the four previous Super Bowls. By the end of the season, they would tie with the Green Bay Packers for having the best regular season record at 13-3, and would go on to win the Super Bowl the following year, and again at Super Bowl XXXIII in 1999, which Homer went to in Season 10's "Sunday, Cruddy Sunday". As of 2016, the Denver Broncos have been to the Super Bowl four times, winning three, the latest in 2016. The Dallas Cowboys haven't even reached the Conference Championships since the airing of the episode. Hilarious, indeed. And for extra hilarity, the Bronco's sole loss in those four games, a crushingly disappointing defeat of 43-8 at Super Bowl XLVIII in 2014, allowed the end of episode scene to be memetically mutated again. Football history has gotten a lot of mileage out of this joke.
Actually, the Broncos have typically been very competitive for the bulk of the franchise's history. As mentioned, they went 13-3 the season in which this episode aired. They were 8-8 the season before, which is the definition of mediocre but not nearly as inept as Homer perceived them to be. Perhaps his opinion was clouded by the team's disastrous Super Bowl results (the first of which came at the hands of the Dallas Cowboys in Super Bowl XII) prior to finally winning one.
Magnificent Bastard: Hank Scorpio, no doubt. SPECTRE might've been able to actually accomplish something if they took some management lessons from this guy.
Unintentionally Unsympathetic: While Bart and Lisa had genuine reasons to be unhappy, Marge was spared the drugery of being a housewife, yet she just moped about having nothing to do. She could've done a million things: paint, get a job, make friends, something...
