These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Just Here for Godzilla: The main event is the game, obviously, but this game attracts a peripheral crowd only there for:
The commercials, which are often some of the most entertaining of the year. Companies spend a pretty penny just buying the slots — they often pour it on for the commercial, too. Even non-football fans talk about the commercials at the water cooler the next day.
The halftime show, which usually features a big name in music doing a few of their top hits.
Never Live It Down: As this is arguably the largest possible athletic stage in the U.S., certain plays and players will never be forgotten, for better or for worse.
Super Bowl I: Fred "The Hammer" Williamson of the Kansas City Chiefs boasted before the game he would aim to take either of the Green Bay Packers' starting wide receivers out of the game with one of his trademark vicious hits. Ironically, Williamson himself would be carried off the field later after being inadvertently kneed in the head on the tail end of a short running play, and wouldn't return. Cameras on the Packers sideline would catch more than a few on the Packers bench snickering over this turn of events.
Super Bowl VI: Miami Dolphins quarterback Bob Griese ended up leading the Dolphins to two consecutive titles (in the games following this one), but he will always be best known for being pressured backwards by the Dallas Cowboys pass rush and being dropped by Bob Lilly for a still-record 29-yard sack.
Super Bowl VII: The Dolphins again, as kicker Garo Yepremian had his field goal attempt blocked and had the ball bounce back to him. He tried to pass, but the ball slipped out of his hand and was immediately picked off by the Redskins' Mike Bass and returned for a touchdown. The Dolphins would win the game to complete their undefeated season, and as it happened, Yepremian and Bass would go on to become good friends afterwardsnote (the two had previously been teammates with the Detroit Lions in 1967).
Super Bowl XIII: The Cowboys' Hall of Fame tight end Jackie Smith found himself wide open in the end zone, lost his footing, and dropped what would have been an easy touchdown pass. The Cowboys settle for a field goal, lose by 4 points in the end to the Pittsburgh Steelers, and Smith is forever immortalized by the announcer's sympathetic call, "Bless his heart, he's got to be the sickest man in America".
Super Bowl XXV: Perhaps the single-most famous play in Super Bowl history, Scott Norwood of the Buffalo Bills barely misses a game winning 47-yard field goal wide right. This is the beginning of the Bills losing 4 straight Super Bowls, all the subsequent ones being complete blowouts. Norwood's career, ironically having been considered a clutch kicker, never recovers. It was so bad that the villain in Ace Ventura: Pet Detective and Buffalo '66 are loosely based on him.
Super Bowl XXVI: Thurman Thomas loses his helmet in the pre-game confusion and misses the first few minutes of the game. Teammate Bruce Smith was still teasing him about it at Smith's Hall of Fame induction 20 years later.
Super Bowl XXVII: Late in a completely one-sided blowout, the Cowboys force a fumble, which is picked up by star defensive tackle Leon Lett and run back for an easy score. However, 10 yards shy of the goal line, Lett slows down and begins to showboat his way into the end zone, sticking the ball carelessly out to his side. Bills wide receiver Don Beebe, one of the fastest men in the league at the time, hustles all the way up the field and slaps the ball out of Lett's outstretched hands just before the goal line, forcing a touchback and turning Lett into a cautionary tale about showboating and a national punchline.
Some years later, after the other flub play that Lett is famous for, he received a letter from a fan, telling him to not feel down, and describing some player in the Super Bowl, who got a sure touchdown knocked out of his hands while showboating... that someone, of course, was Lett.
Super Bowl XXXVII: Oakland Raiders go up against a Tampa Bay Buccaneers squad being led by their previous coach Jon Gruden. Having used Gruden's playbook to get this far, it never occurs to the team to make changes to their offensive scheme. Gruden meanwhile has the Bucs practice while mimicking Raiders QB Rich Gannon on the practice squad, even down to Gannon's snap count cadence. Come game-time, the Raiders get manhandled by a Buccaneers defense that recognizes nearly every play Gannon calls out.
Rubbing salt into the wound, that Super Bowl loss led to a decade-long decline in the Raiders' fortunes where they suffered double-digit losing seasons for seven straight years and for nine out of ten years.
Super Bowl XLVII: In the middle of the third quarter, after the Ravens had taken a significant lead, the lights in the New Orleans Superdome went out for over a half-hour. Pretty much everyone involved was mocked over this, from the hapless announcers, who had to blather about nothing before the largest audience in the world to the commissioner himself who was accused of shutting off the lights on purpose by the winning Ravens. McDonalds built an entire ad campaign around Joe Flacco and Colin Kaepernick (the starting QBs) hanging out after the game, and the blackouts keep occuring.
Periphery Demographic: The largest ones ever, as many, many people watch only for the commercials and a smaller, yet significant group watch for the halftime show.
