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.
They Wasted a Perfectly Good Character: Hank Scorpio, as mentioned in the main YMMV section, is polite for a super-villain and is one of the few people who are genuinely friendly and helpful towards Homer. What's worse is that he wasn't used as the villain in The Simpsons Movie because the writers were afraid of turning him into an all-out villain (when really, they could have left him the way he was and just ramped up his plots for world domination).
